20080292032 | Arrangements for interference mitigation utilizing estimation - A method is disclosed for interference mitigation which can include receiving a signal having a data component, an interfering component and a time period and creating a first plurality of digitized data that represents at least a portion of the interfering component. The method can also include generating a polynomial equation that is related to the at least a portion of the interfering component and generating a second plurality of digital data that represents a data vector of the received signal. The method can further subtract the polynomial equation from the received signal to cancel at least a portion of the interfering component to provide an interference mitigated signal representing the data component. | 11-27-2008 |
20080292033 | Arrangements for acquiring and using data obtained from received interference to facilitate data recovery - In some embodiments a method is disclosed for detecting periodic interference and predicting future interference times. The method can include detecting an arrival time of a first occurrence of interference and detecting an arrival time of a second occurrence of interference. The method can include transmitting preemptive interference mitigation control signals that anticipate future arrival times of interference. A system is disclosed that includes a periodicity detector, an interference profiler and a mitigation control module. The system can provide interference mitigation features to a data recovery system. Other embodiments are disclosed. | 11-27-2008 |
20080292034 | Arrangements for interference mitigation utilizing recursive estimation - A method is disclosed that includes receiving a signal having a data vector component and an interfering component and creating a first set of digitized data that represents the interfering component. The method can also generate a polynomial equation based on the first set of digitized data and generate a second set of digitized data that represents a data vector component of the received signal. The polynomial equation can be subtracted from the received signal to cancel at least a portion of the interfering component and provide an interference mitigated signal representing the data vector component. An error in the interference mitigated signal can be determined and the interference mitigated component can be recalculated based on the error. Other embodiments are also disclosed. | 11-27-2008 |
20080299932 | Arrangements for narrow band interference detection - A method is disclosed for mitigating narrowband interference within a system for wideband communications. The method can include separating a wideband signal into a plurality of sub bands, detecting energy levels in the sub-bands, and activating a control signal if the energy levels of the sub-bands differ by a predetermined amount. Such a difference in energy levels can indicate that narrowband interference is present and interference mitigation features can be activated. In another embodiment, a system is disclosed that has a band splitter and a plurality of energy level detectors to detect energy differences in the sub bands. Other embodiments are also disclosed. | 12-04-2008 |
20090259907 | Inter-packet selective symbol mapping in a joint incremental redundancy and symbol mapping diversity system - An integrated incremental redundancy symbol mapping diversity system for a communication device. The integrated incremental redundancy symbol mapping diversity system includes a transmitter. The transmitter packetizes a retransmission packet according to a modulation scheme in response to a retransmission request from the receiver. The transmitter includes an output packet processor and an inter-packet selective symbol mapper. The output packet processor determines a transmission iteration of a bit segment of the retransmission packet. The inter-packet selective symbol mapper applies a first symbol map pattern to the bit segment based on the transmission iteration of the bit segment and applies a second symbol map pattern to another bit segment of the retransmission packet based on the transmission iteration of the other bit segment. The first symbol map pattern is different from the second symbol map pattern. | 10-15-2009 |

20140159856 | SENSOR HIERARCHY - In general, systems/devices consistent with the present disclosure may be configured to interact with (e.g., receive information from and/or control the operation of) sensors organized based on a hierarchy. The term hierarchy, as referenced herein, may describe an arrangement of items (e.g., sensors) into leveled groups organized based on at least one criterion including, for example, ability, complexity, energy consumption, etc. In one embodiment, a system/device may comprise, for example, at least one first level sensor, at least one second level sensor and a sensor control module. The first level sensor may be configured to generate first level sensor information based on sensing an event. The sensor module may be configured to control operation of the at least one second level sensor based on the first level sensor information. | 06-12-2014 |
20140179295 | DERIVING ENVIRONMENTAL CONTEXT AND ACTIONS FROM AD-HOC STATE BROADCAST - Context state decisions of other users, based on the state of their mobile devices in the vicinity, are used to determine if it reasonable to have your device make or suggest a similar state change. By broadcasting state changes or identifiable actions to all other devices in the vicinity using short-range communications, devices can anonymously notify others in their vicinity of actions they or their users have taken. By collecting and analyzing these notifications, devices can then build their own understanding of the current context and autonomously decide on appropriate actions to take for themselves. | 06-26-2014 |

20100177857 | INTERFERENCE IN COMMUNICATION DEVICES - A wideband signal comprising both a wanted signal and narrowband interference is received in a wideband receiver. The receiver comprises an interference detection unit comprising a set of sub-band filters. With the aid of the sub-band filters the received signal is processed to detect a sub-band containing the narrowband interference in time domain. | 07-15-2010 |
