Abstract

A communication station for use in a CDMA communication system comprising: an antenna system including a plurality of antennas for receiving CDMA communication signals; an adder associated with said antennas and having an output to emit a combined signal; a first of said antennas directly coupled to said adder; a second of said antennas associated with a first delay unit that imparts a first fixed delay to the signals received by said second antenna; and said first delay unit being coupled to said adder, whereby a combined signal is emitted having a known distortion corresponding to at least said first fixed delay; a receiver coupled to the output of said adder; and a modem for receiving an individual communications signal associated with a unique CDMA code coupled to said receiver, said modem including distortion-compensation means for compensating for at least said known signal distortion.
