20120142386 | METHOD AND SYSTEM TO MAKE CURRENT WIRELESS RADIOS COGNITIVE USING AN EXTERNAL SENSOR AND APPLICATION LEVEL MESSAGING - A system and method for converting a non-cognitive radio into a cognitive radio is presented. A cognitive radio system includes, a non-cognitive radio; an electronic device, a spectrum sensing logic and configuration and management logic. The electronic device is connected to the non-cognitive radio so that it receives and/or transmits messages to/from a wireless network. The configuration and management logic is connected between the non-cognitive radio and the spectrum sensing logic. The spectrum sensing logic and the configuration and management logic are removable from the non-cognitive radio allowing the cognitive radio to operate in a non-cognitive mode. The spectrum sensing logic senses a wireless environment to determine available frequencies and available channels. The configuration and management logic transmits available frequencies, available channels or other spectrum data to a remote spectrum manager that is managing access to the wireless network. | 06-07-2012 |
20120250595 | Power aware scheduling and power control techniques for multiuser detection enabled wireless mobile ad-hoc networks - What is provided is a system for maintaining acceptable error rates in a MUD-enabled ad-hoc network. In this system the power spread associated with all of the nodes is maintained within the dynamic range of the system, for instance 30 dB. Also, the signal-to-noise ratio at an intended receiver is maintained above a predetermined minimum SNR, for instance above 5 dB. If the dynamic range rule is not met, then the power at the transmitting node is attenuated such that the dynamic range rule is met, checking to see that the minimum SNR rule is also met, or the transmission from this node is pulled. If there is no power control solution, then power aware scheduling is applied. Alternatively, only power aware scheduling is utilized. | 10-04-2012 |
20120250629 | MULTIUSER DETECTION ENABLED MEDIUM ACCESS CONTROL IN MOBILE AD HOC NETWORKS - A method of providing medium access control for a wireless mobile ad hoc network includes defining a TDMA network timing frame including a data (DATA) zone having one or more time slots structured to support multiuser detection (MUD) of concurrent transmissions during each slot, a negative acknowledgment (NACK) zone during which nodes transmit requests for retransmission of packets destined to but not successfully received by the nodes, a broadcast (BC) zone during which network management messages are broadcast to the nodes, and a control (CTRL) zone. A primary master (PM) node is selected and operates as a source of network time for all the nodes. Each node synchronizes its time to that of the PM node during the CTRL zone in a distributed manner, by exchanging control messages with the PM node or other nodes located one or more hops from the PM node. | 10-04-2012 |
20120250632 | DISTRIBUTED SCHEDULER DESIGN FOR MULTIUSER DETECTION ENABLED WIRELESS MOBILE AD-HOC NETWORKS - In the method for operating an interference multiple access communications system, wherein the improvement comprises the steps of employing a distributed scheduler within a Media Access Controller (MAC) for Multiuser Detection (MUD) enabled Mobile Ad-hoc Networks (MANETS) to increase spectral efficiency by increasing spectral use and providing a way to dynamically allocate virtual channels to achieve maximum channel reuse in different network topologies and different link patterns and to ameliorate any hidden or exposed node problems. | 10-04-2012 |
20130315162 | Systems And Methods For Creating Non-Orthogonal Dimensionality Between Signals In Electronic Devices - Systems and methods for creating non-orthogonal dimensionality between signals are disclosed. Signals are received from at least one electronic device. An adjustment of a parameter of a received signal of a first device of the at least one of the electronic device that would result in an adjusted signal that is not orthogonal but differentiates the signal from at least one other signal of the received signals is determined. An instruction is communicated to the first device to implement the adjustment of the parameter. | 11-28-2013 |
20140067739 | REDUCTION OR ELIMINATION OF TRAINING FOR ADAPTIVE FILTERS AND NEURAL NETWORKS THROUGH LOOK-UP TABLE - A system and method of reducing or eliminating training for adaptive receiver and neural networks is disclosed. The adaptive filter or neural network is pre-training using simulation or empirically received data and a took-up table is created. Coefficient instantiation from the receiver for ail permutations of the key parameters of training data are stored along with the key parameters within the look-up table. After creating the look-up table, the key parameters of the signal to be decoded are estimated. The coefficient of filter or neural network for the estimated key parameters is obtained by accessing the loop-up table. The demodulated signal is produced by setting the filter or neural network coefficents to coefficient values obtained from the look-up table. For slow varying key parameters, the coefficients from the lookup table are occasionally replaced instead of implementing the adaptive filter or neural network. | 03-06-2014 |
20140369269 | Methods And Systems For Processing Communications Between A Base Station And Mobile Device Based On Wireless Communciations Of Another Base Station - Methods and systems for processing communications based on wireless communications of adjacent base stations are disclosed.

Further, the method includes processing communications between the first base station and the one or more other mobile devices based on the wireless communication scheme. | 12-18-2014 |
20150085679 | Methods, Systems, And Computer Program Products For Parameter Estimation Based On Historical Context Information - Methods and systems are described for parameter estimation based on historical context information. In one aspect, a communication context for a first mobile device is determined. The communication context is compared to a stored historical communication context of at least one other mobile device, wherein the stored historical communication context includes at least one of communication parameter estimates, mobile device statistics, mobile device transmit settings, and base station receiver settings. Parameters for communicating with the first mobile device are estimated based on the comparison. | 03-26-2015 |
