Abstract  Abstract

A CDMA INTERFERENCE CANCELER PER BROADENED SPECTRUM TO REDUCE INTERFERENCE IN A DS / CDMA RECEIVER THAT HAS CHIP N. CODE CHANNELS INCLUDES A PLURALITY OF CORRELATORS (54,64,74), A PLURALITY OF CIRCUITS PROCESSING BY SPLIT SPECTRUM (55,65,75), SUBTRACTION CIRCUITS (150), AND CHANNEL CORRELATORS (146). USING A PLURALITY OF CHIP CODE SIGNALS GENERATED FROM CHIP CODE WORD SIGNAL GENERATORS (52,62,72), CORRELATORS (54,64,74) DETACH THE CDMA SIGNAL BY SPLITTED SPECTRUM AS A PLURALITY OF DISENGAGED SIGNALS. THE PLURALITY OF SPREADED SPECTRUM PROCESSING CIRCUITS (55,65,75) USES A TIMED VERSION OF THE PLURALITY OF CHIP CODE SIGNALS GENERATED FROM THE DELAYED DEVICES (53,63,73), FOR THE PROCESSING OF SPREADED SPECTRUM OF THE PLURALITY OF DISENGAGED SIGNALS. TO RETRIEVE A CODE CHANNEL USING A CHIP I {SUP, TH} CODE SIGNAL, THE SUBSTRATION CIRCUITS (150) SUBTRACT THE CDMA SIGNAL BY SPREADED SPECTRUM, EACH OF THE DISENGAGED SIGNALS PROCESSED BY NARROW SPECTRUM-1 FROM WHICH AN UNDERSTANDED SIGNAL IS GENERATED. THE CHANNEL CORRELATOR (146) DETACHES THE UNDERSTANDED SIGNAL.
