Abstract :
This paper describes an eigen-structure-based (ESB) filtering algorithm for suppressing a strong tone interference source in direct sequence spread spectrum (DSSS) communication systems. The effectiveness of the proposed algorithm is illustrated by comparing its bit error rate (BER) performance with a LSM-based algorithm through computer simulated experiments
