The Widrow LMS algorithm is considered for the implementation of an adaptive prewhitening filter in a direct sequence (DS) spread spectrum receiver. Usin an approximation for the statistics of the output of the adaptive filter, expressions for the resulting bit-error-rate (BER) when the adaptive algorithm is used to suppress a fading tone jammer are developed, and numerical results obtained from these expressions are compared with simulation results for the DS receiver.
