Abstract :
We use computer simulations to compare the performance improvements associated with coding on a Gaussianized BPSK-MC-DS-CDMA system and a non-Gaussianized DPSK-MC-DS-CDMA system. The effects of coding on the Gaussianized system approach the performance of a coded BPSK system operating in a Gaussian channel while the non-Gaussianized system performance is approximately 4 dB from the coded DPSK system operating in a Gaussian channel
