Mc-cdma Technology And Research

Multi Carrier-Code Division Multiple Access (MC-CDMA) is a new Multi-Carrier modulating technology for broadband mobile wireless communication. MC-CDMA combined the advantage of OFDM and CDMA. In high speed data transmitting, the performance of MC-CDMA is obviously more excellent than DS-CDMA. This article emphasized studied on the performance of MC-CDMA and put forward the realization project based on DSP and FPGA.This article introduced the development of MC-CDMA and related technology, emphasized introduced the theory of OFDM and MC-CDMA, put forward the math model of MC-CDMA. After simulated the constellation and time signal, the article simulated the performance of MC-CDMA, compared the BER of DS-CDMA and MC-CDMA in the same channel parameter. The article validated the effective of BER on BPSK, QPSK, 16PSK modulation, prefix and multichannel. Finally introduced a project of MC-CDMA based on DSP and FPGA.This article established a model of MC-CDMA's design, simulation based on researched OFDM. At the same time, article provided useful reference project and data for system realization.
