A comparative performance study of excisers in spread spectrum communications
The comparative performance of a direct-sequence spread-spectrum (DSSS) receiver for different excisers is presented. The performance of the adaptive time-frequency (ATF) exciser is ranked along with fixed and optimal transform domain-based excisers. The smart ATF exciser is able to decide on the domain of processing. For the 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.
