Patent ID: 6876665

Claim:
A method employed by a remote terminal for reducing interference in a spread spectrum code division multiple access (CDMA) receiver having N channels wherein each of the N channels is identified by a distinct chip-code signal, comprising: a) generating a plurality of chip-code signals; b) simultaneously despreading a plurality of spread spectrum channels of a spread spectrum CDMA signal; c) generating a timed version of the plurality of chip-code signals; d) spread spectrum processing the plurality of despread signals with a chip-code signal corresponding to a respective despread signal; e) subtracting from the spread spectrum CDMA signal N−1 spread spectrum process despread signals with N−1 spread spectrum process despread signals with the exception of a spread spectrum process despread of an i th despread signal to general a subtractive signal; and f) despreading a subtractive signal employ the i th chip-code signal as an i th channel.
