This paper presents a Higher Order Statistic Matched Filter (HOSMF) receiver whichuse in signal detection of PN-sequence in the presence of the Gaussian and nonGaussian noise. We also propose a method for the realization of a correlator to computethe 3rd order cumulant. The PN-sequence is detected via multiple correlation andcumulants, respectively.The detection algorithm is computationally simply and condrary to standard matchedfilter, it is insensitive to shift pn-sequence and does not required knowledge of the noisespectrum for pre whitening. The receiver can be viewed as like hood ratio test betweensampled higher order statics. Simulation illustrated successful performance of thedetection using correlation higher order statics matched filter (HOSMF) than theconventional MF under certain types of noise.
