Abstract  Abstract

A method for reducing interference in a direct sequence CDMA receiver the method comprising the steps of: a) despreading a received spread spectrum signal for each of a plurality of CDMA channels to produce a first estimate for each channel; b) for each channel spreading the estimate obtained from the prior step for all of the other channels to produce spread other channel signals and subtracting the spread other channel signals from the received signal and despreading the subtracted result to produce a next estimate for that channel; c) repeating step b) a selected number of times; and d) combining the estimates for each channel produced by steps a) b) and c) to output a channel signal for each channel.
