Abstract :
The rejection of PSK interference in a DS-SS/QPSK using a complex adaptive filter and a nonlinear receiver with soft-limiter is discussed. This system leads to a decrease in error probability of several orders of compared to a system which uses a complex adaptive filter and a linear receiver
