Abstract:
A CDMA subscriber unit comprising:a plurality of selectively spaced omnidirectional antennas, each for receiving CDMA communication signals within the operating range of the subscriber unit; a summer associated with said antennas and having an output for outputting a combined signal; a first of said antennas directly coupled to said summer; each subsequent antenna of said plurality of antennas associated with a respective delay unit, each respective delay unit being coupled to said summer and each respective delay unit imparting a different fixed delay to the signal received by the respective antenna, each fixed delay resulting in a delay of at least two chips relative to each other delay; the delayed signals being combined with the signal of said first antenna by said summer, said combined output signal having a known phase distortion corresponding to the fixed delays; a receiver coupled to the output of said summer; and a modem for receiving an individual communication signal associated with a unique CDMA code, said modem including distortion-compensating means for compensating for at least said known phase distortion.
