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.
