ABSTRACT:
A means for reducing side lobe signals and noise signals generated in a correlator in N chip positions for correlating a received input signal with a reference signal. The coincidence and non-coincidence indicating signals of first and second halves of the chip positions of the correlator are added together separately and then subtracted one from the other, with the resulting difference signal then being rectified. Such rectified difference signal which contains the side lobe signals and the noise signals but not the desired correlator indicating signal, is subtracted from the total summed and rectified signals generated by all of the N chip positions of said correlator to produce a resultant signal with much of the side lobe signals and the noise signals cancelled out.
