摘要： Wireless receivers are described for receiving signals from a transmitter. A receiver can include a plurality of antennas each for receiving a version of a signal via a different propagation channel and providing that version to a respective input. Signal processing means can be included and configured to operate diversity processing of a supplied number of said inputs for use in performing detection of said signal. The receiver can include channel parameter estimation means, configured to estimate one or more channel parameters on the propagation channels. The receiver can also include selection means configured to select only a subset of said inputs to implement a specific dimensionality of the receiver diversity processing, in dependence on the one or more channel parameters indicative of channel conditions on said propagation channels. The diversity processing can be linear or non-linear. Related methods and software implementations and computer program products are also described.

摘要： Method, receiver and computer program product for processing a signal transmitted from a plurality of spatially separated transmit antennas using a Multiple-Input Multiple-Output transmission over a wireless network. The signal is received at a plurality of spatially separated receive antennas, the signal comprising a plurality of data streams and the quality/reliability of each of the data streams in the received signal is determined. Based on the determined quality/reliability of the data streams, a decoding technique is selected to be one of (i) a successive decoding technique for successively decoding data streams in which one of the data streams is decoded and a signal corresponding to said one of the data streams is removed from the received signal prior to decoding further data streams in the received signal, and (ii) a non-successive decoding technique in which each data stream is decoded from the received signal by treating the other data streams as noise in the received signal. The received signal is then decoded using the selected decoding technique.
