    Abstract

    The performance of a direct-sequence spread-spectrum (DS-SS) receiver employing new techniques for multiple non-stationary interference suppression is presented. These techniques are based on transform domain order statistics and they selectively suppress spectral components that are sufficiently large and narrow. Other important advantages are also discussed. The bit error rate performance is determined by Monte-Carlo simulations and it is compared to the performance of fixed notch filtering and of the well-known LMS algorithm. The effect of using data windowing is examined, and results with single-tone, narrow-band, stationary, non-stationary and multiple interference are presented. A comparison of the amount of computation required by the proposed transform domain approach to that of the time-domain LMS algorithm is also presented.
