Performance of coded direct sequence spread spectrum in a fading dispersive channel with pulsed jamming
Consideration is given to the performance of a binary phase-shift-keyed (BPSK) direct-sequence spread-spectrum (DS/SS) communication system in a fading dispersive channel with the direct or specular component of the signal present. Two types of multipath intensity profiles are analyzed. Large values...

Summary: | Consideration is given to the performance of a binary phase-shift-keyed (BPSK) direct-sequence spread-spectrum (DS/SS) communication system in a fading dispersive channel with the direct or specular component of the signal present. Two types of multipath intensity profiles are analyzed. Large values of the multipath spread (larger than a symbol duration) are considered, and a useful approximation to the symbol error probability, based on random spreading sequences, is derived. The effect of pulsed jamming on the performance is analyzed. Both the uncoded and the coded case are considered. In the coded case, hard- and soft-decision decoding metrics, with and without jammer-state information (JSI), are analyzed and discussed.< > |
