    • A wireless receiver and corresponding method for receiving a signal transmitted by a transmitter. The receiver comprises: a plurality of antennas each for receiving a version of the signal via a different propagation channel and providing that version at a respective input, and signal processing means configured to operate diversity processing of a supplied number of the inputs for use in performing detection of the signal. The receiver further comprises: channel parameter estimation means configured to estimate one or more channel parameters on the propagation channels; and selection means configured to select only a subset of the 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 the propagation channels.
    • 一种用于接收由发射机发射的信号的无线接收机和相应的方法。 接收机包括:多个天线,每个天线用于经由不同的传播信道接收信号的版本并且在相应的输入处提供该版本;以及信号处理装置,配置为操作所提供的多个输入的分集处理以用于执行 信号的检测。 接收机还包括:信道参数估计装置,被配置为估计传播信道上的一个或多个信道参数; 以及选择装置,被配置为根据指示传播信道上的信道条件的一个或多个信道参数,仅选择输入的子集来实现接收机分集处理的特定维度。
