Abstract
Receiver processing techniques for demodulating pseudo-noise (PN) spread spectrum signals that are corrupted by narrowband interference and/or channel multipath are described. Narrowband interference is suppressed by means of a linear transversal notch filter (noise-whitening filter) with coefficients that are determined from linear prediction algorithms. Several techniques are considered for mitigating the time-dispersive effects of the interference suppression filter and the channel multipath. The techniques are compared on the basis of their error rate performance.
