Claim One:
1. An apparatus for processing a received wireless communication signal, comprising: an input for receiving a sample vector which includes a plurality of sample values and which represents a timewise corresponding wireless communication signal portion received via a plurality of receive antennas and produced by a transmitter in which each of a plurality of information sources transmits a plurality of symbols via respective ones of a plurality of transmit antennas during each of a plurality of transmit time intervals associated with said wireless communication signal portion; an input processing section coupled to said input for producing from the sample vector a plurality of vectors that are smaller than the sample vector; an interference rejection unit coupled to said input processing section for applying an interference rejection operation to each of said smaller vectors individually to thereby decide said symbols; wherein said input processing section including a chip equalizer coupled to said input for applying a chip equalization operation to said sample vector to thereby produce a chip equalization result vector; wherein said input processing section includes a separator coupled to said chip equalizer for separating said chip equalization result vector into a plurality of intermediate vectors; and wherein said input processing section includes a despreader coupled between said interference rejection unit and said separator for applying a plurality of spreading codes to said intermediate vectors to effectuate a despreading operation that produces said smaller vectors.
