Efficient simulation of coded MC-DS-CDMA systems

We use computer simulations to compare the performance improvements associated with coding on a Gaussianized binary phase-shift keying (BPSK) multicarrier direct-sequence code-division multiple-access (MC-DS-CDMA) system and a nonGaussianized differential phase-shift keying (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.
