Abstract: Systems and methods that provide channel-adaptive antenna selection in multi-antenna element communication systems are provided. In one embodiment, a method that selects a subset of receive antennas of a receiver to receive a transmitted RF signal may include, for example, one or more of the following: establishing possible subsets of the receive antennas; determining sets of channel parameter statistics corresponding to the possible subsets of the receive antennas; computing output bit error rates of the receiver, each output bit error rate being computed based on at least one set of channel parameter statistics; selecting a particular possible subset of the receive antennas based upon a criterion predicated on the computed output bit error rates; and connecting one or more RF chains of the receiver to the receive antennas of the selected particular possible subset.

Abstract: Methods and systems for processing signals in a wireless communication system are disclosed. Aspects of the method may include calculating at a receiver, a plurality of energy values corresponding to a plurality of signal paths detected within a communication channel. At least one of the plurality of detected signal paths may be selected for processing based on a pre-defined threshold and a dynamic threshold, in order to achieve a desired probability of misdetection and a desired probability of false alarm. The probability of misdetection is a probability that a real signal path is missed, and the probability of false alarm is a probability of detecting a false signal path. A slot boundary, a frame boundary, and/or a scrambling code may be determined for signals communicated via said plurality of signal paths.

Abstract: Methods and systems for processing signals in a receiver are disclosed herein and may include updating a plurality of filter taps utilizing at least one channel response vector and at least one correlation vector, for a plurality of received clusters, based on initialized values related to the at least one channel response vector and the at least one correlation vector. At least a portion of the received signal clusters may be filtered utilizing at least a portion of the updated plurality of filter taps. The update may be repeated whenever a specified signal-to-noise ratio (SNR) for the received signal clusters is reached. The initialized values may be updated during a plurality of iterations, and the update may be repeated whenever a specified number of the plurality of iterations is reached.
