In this paper, we evaluate the performance analysis arepresented inthis performance ofLDPCcoded MC-CDDMA in paper. Rayleigh fading channels.

Insection III, themaximal ratio combining numberofiterations inLDPC decoding.(MRC)andminimummeansquare error Compared toturbo codedMC-CDMA,the combining (MMSEC)aredescribed. In LDPCcodedMC-CDMAhasadvantages in section IV,we investigate themultiuser BER performance andcomplexity.
