Abstract

The authors investigate the performance of two types of direct-sequence spread-spectrum multiple-access (DS/SSMA) systems in an impulsive noise, Rician fading environment. It is observed that it is possible to get some coding gain over uncoded systems except at low SNR and that additional coding gain can be obtained by using optimum asymmetric TCM. It is also shown that the performance of the DS/SSMA systems degrades more as the noise becomes more impulsive
