Abstract  Abstract

A method for reducing interference subtractive interference canceller in the spread spectrum receiver with N channels wherein in the N channels of each of the different sheet code signal identification the subtractive interference canceller comprises: a plurality of device generating a plurality of chip-code signal a plurality of despreading device for simultaneously the plurality of spread spectrum channel spread signals are spread forming multiple despread signal a plurality of device a plurality of chip-code signal to the plurality of chip code signal timing so as to respectively generate timing version; a plurality of chip-code signal in response to the timing version a plurality of device simultaneously performs spread spectrum processing the plurality of despread signal for the ith chip-code signal for simultaneously subtracting each to generate subtracted signal of device N-1 de-spread signal spread spectrum processing in the delay through the delay means of the spread-spectrum CDMA signal and is used for the ith chip code signal to the subtracting signal spread forming the ith channel of the channel device.
