On parasitic correlation peaks in crosscorrelation circuits for binary pseudorandom sequences
Abstract
Technical applications of binary pseudonoise (PN) sequences frequently utilize correlation procedures. At the output of the postdetection integrator of one form of the correlation circuit, which is often used to obtain initial synchronization of PN spreadspectrum communications systems, parasitic voltage peaks may appear which are not evident from the basic theory of pseudorandom sequences. The origin of these parasitic peaks is explained by the help of the shiftandadd property of binary pseudorandom sequences. Besides, a procedure is given for the approximate calculation of the amplitude of the parasitic peaks.
