20160033613 | SYSTEM AND METHODS FOR INFORMATION COLLECTION AND PROCESSING FOR LOCATION ESTIMATION IN MIMO WIRELESS NETWORKS - Disclosed herein, one embodiment of the disclosure is directed to a system, apparatus, and method for location estimation in the presence of multipath/non-line-of-sight (NLOS) conditions. Various methods have been contemplated to detect the level of multipath/NLOS propagation between two devices. A SNR variation method determines how the SNR of each chain/stream is varying over a time window in order to detect the chain/stream with least local scattering or multipath. A measure of coherence SNR is defined to measure the level of multipath/N LOS per-chain/stream. Moreover, since per-subcarrier SNR information is available at the one or both nodes, the coherence methods can be used on a per-subcarrier basis to detect multipath/NLOS for the entire channel, for the specific spatial stream or for the specific frequencies occupied by the subcarriers. Furthermore, a coherence bandwidth estimation method uses the SNR variation over subcarriers to detect the coherence bandwidth of the spatial stream. The amount of multipath/NLOS is inversely proportional to the coherence bandwidth. | 02-04-2016 |

20130159684 | BATCHED REPLAYS OF DIVERGENT OPERATIONS - One embodiment of the present invention sets forth an optimized way to execute replay operations for divergent operations in a parallel processing subsystem. Specifically, the streaming multiprocessor (SM) includes a multistage pipeline configured to batch two or more replay operations for processing via replay loop. A logic element within the multistage pipeline detects whether the current pipeline stage is accessing a shared resource, such as loading data from a shared memory. If the threads are accessing data which are distributed across multiple cache lines, then the multistage pipeline batches two or more replay operations, where the replay operations are inserted into the pipeline back-to-back. Advantageously, divergent operations requiring two or more replay operations operate with reduced latency. Where memory access operations require transfer of more than two cache lines to service all threads, the number of clock cycles required to complete all replay operations is reduced. | 06-20-2013 |
20130166877 | SHAPED REGISTER FILE READS - One embodiment of the present invention sets forth a technique for performing a shaped access of a register file that includes a set of N registers, wherein N is greater than or equal to two. The technique involves, for at least one thread included in a group of threads, receiving a request to access a first amount of data from each register in the set of N registers, and configuring a crossbar to allow the at least one thread to access the first amount of data from each register in the set of N registers. | 06-27-2013 |
20130212364 | PRE-SCHEDULED REPLAYS OF DIVERGENT OPERATIONS - One embodiment of the present disclosure sets forth an optimized way to execute pre-scheduled replay operations for divergent operations in a parallel processing subsystem. Specifically, a streaming multiprocessor (SM) includes a multi-stage pipeline configured to insert pre-scheduled replay operations into a multi-stage pipeline. A pre-scheduled replay unit detects whether the operation associated with the current instruction is accessing a common resource. If the threads are accessing data which are distributed across multiple cache lines, then the pre-scheduled replay unit inserts pre-scheduled replay operations behind the current instruction. The multi-stage pipeline executes the instruction and the associated pre-scheduled replay operations sequentially. If additional threads remain unserviced after execution of the instruction and the pre-scheduled replay operations, then additional replay operations are inserted via the replay loop, until all threads are serviced. One advantage of the disclosed technique is that divergent operations requiring one or more replay operations execute with reduced latency. | 08-15-2013 |
20130232322 | UNIFORM LOAD PROCESSING FOR PARALLEL THREAD SUB-SETS - One embodiment of the present invention sets forth a technique for processing load instructions for parallel threads of a thread group when a sub-set of the parallel threads request the same memory address. The load/store unit determines if the memory addresses for each sub-set of parallel threads match based on one or more uniform patterns. When a match is achieved for at least one of the uniform patterns, the load/store unit transmits a read request to retrieve data for the sub-set of parallel threads. The number of read requests transmitted is reduced compared with performing a separate read request for each thread in the sub-set. A variety of uniform patterns may be defined based on common access patterns present in program instructions. A variety of uniform patterns may also be defined based on interconnect constraints between the load/store unit and the memory when a full crossbar interconnect is not available. | 09-05-2013 |
20130268715 | DYNAMIC BANK MODE ADDRESSING FOR MEMORY ACCESS - One embodiment sets forth a technique for dynamically mapping addresses to banks of a multi-bank memory based on a bank mode. Application programs may be configured to perform read and write a memory accessing different numbers of bits per bank, e.g., 32-bits per bank, 64-bits per bank, or 128-bits per bank. On each clock cycle an access request may be received from one of the application programs and per processing thread addresses of the access request are dynamically mapped based on the bank mode to produce a set of bank addresses. The bank addresses are then used to access the multi-bank memory. Allowing different bank mappings enables each application program to avoid bank conflicts when the memory is accesses compared with using a single bank mapping for all accesses. | 10-10-2013 |

The interference compensation signal is generated by adjusting at least one of amplitude, phase, and delay of the samples to emulate the interference imposed on the victim antenna. | 10-20-2011 |
20130064382 | Pre-Configuration and Control of Radio Frequency Noise Cancellation - A noise-reduction system includes a noise-pattern predictor in communication with a noise-canceling module. In a more specific embodiment, the noise-reduction apparatus further includes an input collector in communication with the noise-pattern predictor. The input collector is coupled to a first module, such as a sensor, that provides information to the noise-pattern predictor to facilitate predicting noise in an accompanying signal environment and to provide a first signal in response thereto. In an illustrative embodiment, the first signal includes information indicating when an ignition system of a vehicle will turn on. The first signal further includes information indicating when a second signal transmitted from a cellular base station will affect noise in the signal environment. The second signal may include a burst in a cellular signal. | 03-14-2013 |
20130099855 | Filter Shaping Using a Signal Cancellation Function - A signal filter and accompanying methods. In one embodiment, the filter includes a first mechanism for receiving a first signal. A second mechanism employs one or more modified representations of the first signal to cancel one or more frequency components of the first signal, yielding an output signal in response thereto. In a more specific embodiment, the first mechanism includes a splitter for receiving the first signal and splitting the first signal onto a first path and a second path. The second mechanism further includes one or more delay modules and one or more phase shifters in the first path and/or the second path. One or more controllable amplifiers are optionally included in the first path and/or the second path. The one or more delay modules, phase shifters, or amplifiers are responsive to one or more control signals from a controller. The controller is adapted to modify behavior of the second mechanism so that the filter is characterized by a desired frequency response. | 04-25-2013 |
20140206300 | METHODS AND SYSTEMS FOR NOISE AND INTERFERENCE CANCELLATION - Signals propagating from an aggressor communication channel can cause detrimental interference in a victim communication channel. One or more noise cancellers can generate an interference compensation signal to suppress or cancel the interference based on one or more settings. A controller can execute algorithms to find preferred settings for the noise canceller(s). The controller can use a feedback signal (e.g., receive signal quality indicator) received from a victim receiver during the execution of the algorithm(s) to find the preferred settings. One exemplary algorithm includes sequentially evaluating the feedback resulting from a predetermined list of settings. Another algorithm includes determining whether to move from one setting to the next based on the feedback values for both settings. Yet another algorithm includes evaluating a number of sample settings to determine which of the sample settings result in a better feedback value and searching around that sample setting for a preferred setting. | 07-24-2014 |
