Paper Abstract

In this paper, we present the performance of a multitone code division multiple access (MT-CDMA) system by analyzing the effect of coding. We use convolutionally coded substreams rather than serial-to-parallel converted data to modulate different subcarriers. The bit error rate bound for the decoding metric is derived. The coded and uncoded performance bounds are compared with respect to equal bandwidth, bit rate and other communication resources. We also present the performance trade-off for different coded modulation schemes. Our results indicate that the performance of an MT-CDMA is significantly improved when channel coding is applied.
