Abstract

A comparative performance of a direct-sequence spread-spectrum (DSSS) receiver for different excisers is presented. The performance of the recently introduced adaptive time-frequency (ATF) exciser is ranked along with the fixed and optimal transform domain-based excisers. The smart ATF exciser is able to decide on the domain of processing. For narrowband interference case, the ATF exciser employs an adaptive subband filter bank with the best transform basis. The bit error rate performance of DSSS receiver is simulated for ATF, DFT, DCT, optimal KLT, and fixed subband filter bank-based interference cancellers. It is shown that the smart ATF exciser significantly outperforms the others for the scenarios considered. The performance of ATF is very robust to the variations of the interference.
