By Using of the Gamma Variates to Analyze the performance of MC-DS-CDMA System over Selective Fading Channels

Abstract

A new pdf (probability density function) of SNR (signal-to-noise ratio) is proposed such that the complex procedure of traditional method can be abstained. The sum of correlated-gamma variates was considered for evaluating the system performance of MC-DS-CDMA (multi-carrier direct-sequence coded-division multipleaccess) system operating in frequency selective fading channels in this paper. The analysis including multipleuser and single-user, are validating the fact that the performance degradation of the MC-DS-CDMA is sensitive to the correlation coefficient between the fading branches.
