Analysis of DS/SSMA system with hard-limiting correlator over fading channels with impulsive noise

The performance of a DS/SSMA (direct-sequence spread-spectrum multiaccess) system with hard-limiting correlation receivers is analyzed over nonselective Rician fading channels with impulsive noise. More specifically, computation of the average bit-error probabilities of the DS/SSMA system have been accomplished in this paper by exact computation for short spreading sequences and by approximation for long spreading sequences. >
