Z. Nikolic et al., REJECTION OF PSK INTERFERENCE IN DS-SS QPSK SYSTEM USING COMPLEX ADAPTIVE FILTER AND NONLINEAR CORRELATION RECEIVER/, Electronics Letters, 33(7), 1997, pp. 561-562
The rejection of PSK interference in a DS-SS:QPSK system by using a co
mplex adaptive filter and a nonlinear correlation receiver with soft-l
imiter is discussed. This system leads to a decrease in error probabil
ity of several orders of magnitude compared to a system which uses a c
omplex adaptive filter and a linear receiver.
