摘要： There is disclosed a receiver and associated methods in which a received signal can be sampled at the symbol rate rather than oversampled. This reduction in the sampling frequency compared with conventional receivers lowers power consumption. Quality metrics in receiving the data (e.g. packet error rate, etc) are not adversely affected by setting a programmable phase shift in the sampling frequency. The programmable shift can be selected through a calibration process using a known sequence of symbols, such as the short training field in 802.11 standards.

摘要： This invention is related to a low-complexity MIMO detector in a wireless communication system with near optimal performance. Initial symbol estimation is performed for a transmitted symbol vector. The soft information of the transmitted symbol vector can be more accurately calculated by deemphasizing the LLRs associated with symbols belonging to weak channels that may suffer from poor initial estimation. By combining aspects of both the linear detection and the ML detection, the complexity of the proposed detector becomes orders of magnitude lower than that of a ML detector, but the performance is very close to that of an ML detector.

摘要： This invention is related to a low-complexity MIMO detector in a wireless communication system with near optimal performance. An initial symbol estimation is performed for a received symbol vector. The soft information of the received symbol vector can be more accurately calculated using every candidate symbol vector of a combined set of candidate symbol vectors, wherein the combined set is generated based on the initial estimation. By combining aspects of both the linear detection and the ML detection, the complexity of the proposed detector becomes orders of magnitude lower than that of a ML detector, but the performance is very close to that of an ML detector.
