PERFORMANCE OF DS SSMA SYSTEMS USING TCM UNDER IMPULSIVE NOISE ENVIRONMENT/

In this paper, we investigate the effects of impulsive noise on the DS /SSMA systems using TCM. We obtain the probability of bit error bound of the systems, considering both impulsive noise and Rician fading una voidable in mobile communication environments. It turns out that we ca n achieve some coding gain by using TCM under impulsive noise environm ent at moderate to high signal to noise ratio (SNR). It is observed th at the bit error probability is dominated by the background noise vari ance when the SNR is low and by the tail noise variance when the SNR i s high.
