| Abstract: This paper presents a Higher Order Statistic Matched Filter (HOSMF) receiver which use in signal detection of PN-sequence in the presence of the Gaussian and non Gaussian noise. We also propose a method for the realization of a correlator to compute the 3rd order cumulant. The PN-sequence is detected via multiple correlation and cumulants, respectively. The detection algorithm is computationally simply and condrary to standard matched filter, it is insensitive to shift pn-sequence and does not required knowledge of the noise spectrum for pre whitening. The receiver can be viewed as like hood ratio test between sampled higher order statics. Simulation illustrated successful performance of the detection using correlation higher order statics matched filter (HOSMF) than the conventional MF under certain types of noise. | ||
