Abstract  Abstract

A subtractive interference canceller to reduce the interference in the spread spectrum receiver with N channels each of the N-channels by different code-chip signal mark the subtractive interference canceller comprises: a plurality of devices for generating a plurality of chip-code signal a plurality of de-spreading device for the plurality of spread-spectrum channels of spread-spectrum signals are despread into a plurality of despread signals a plurality of device for multi-chip signal of the plurality of chip signal timing so as to respectively generate timing version; in response to a plurality of chip signal version of the timing a plurality of devices for simultaneously performing spread spectrum processing the plurality of despread signals for the ith chip-code signal for simultaneously subtracting N-1 each to generate the subtracted signal of the spread spectrum processing device de-spread signal and for the ith chip-code signal to despreading the subtracted signal into the ith channel of the channel device from the spread-spectrum CDMA signal.
