Performance Analysis of Direct Sequence Differential Phase Shift Keying (ds-dpsk) with Self-normalization and L-fold Diversity in a Fading Channel

The pevormance of a Direct Sequence Differential Phase Shift Keying (DS-DPSK) spread spectrum system employing time diversity and self-normalization over a Ricianfiequency nonselective, slowly fading channel in the presence of pulsed noise interference and additive white Gauxsian noise (AWGN) is considered, An interference model which considers the possibility that either both, one or none of the information bits e~erience jming is employed. Worst case pe~orrnance under severe and moderate fding conditions are analyzed. Results indicate that the self-normalized receiver is effective in mitigating the eflects of pulse noise jamming for all fading conditions considered.
