Abstract  Abstract

A CDMA INTERFERENCE CANCELLER THROUGH SPREADED TO REDUCE THE INTERFERENCE IN A DS / CDMA RECEIVER THAT HAS CHIP CODE CHANNELS N. THE INTERFERENCE CANCELLATOR INCLUDES A PLURALITY OF CORRELIZERS (54,64,74), A PLURALITY OF CIRCUITS PROCESSING BY SPREADED SPECTRUM (55,65,75), SUBSTRACTION CIRCUITS (150), AND CHANNEL CORRELIZERS (146). USING A PLURALITY OF CHIP CODE SIGNALS GENERATED FROM THE CHIP CODE WORD SIGNAL GENERATORS (52,62,72), THE CORRELIZERS (54,64,74) DISCONNECT THE CDMA SIGNAL BY SPREADED SPECTRUM AS A PLURALITY OF DETACHED SIGNALS. THE PLURALITY OF PROCESSING CIRCUITS OF SPLIT SPLITED (55,65,75) USES A TIMED VERSION OF THE PLURALITY OF CHIP CODE SIGNALS GENERATED FROM DELAYING DEVICES (53,63,73), FOR PROCESSING BY SPLITED SPECTRUM OF THE PLURALITY OF DISMANTLED SIGNS. TO RECOVER A CODE CHANNEL USING A CHIP I {SUP, TH} CODE SIGNAL, THE SUBSTRATION CIRCUITS (150) SUBSTRAEN FROM THE CDMA SIGNAL BY SPREADED SPECTRUM, EACH ONE OF THE DISMANTLED SIGNALS PROCESSED BY SPRAYED N-1 ENSANCHED SPECTRUM FROM WHICH AN SUBSTRAID SIGN IS GENERATED. THE CHANNEL CORRELIZER (146) UNPLANK THE SUBSTRAID SIGNAL.
