Abstract

According to the poor error-correcting performance of traditional channel codes in shortwave channel, turbo code whose performance is close to the Shannon limit is introduced. Combined with Multi-Carrier-Code Division Multiple Access (MC-CDMA) technology which can inhibit multi-path interference remarkably, the system of Turbo-MC-CDMA is proposed. Then the effect of MC modulation and turbo coding on the performance of the system is studied, which can provide the reference basis for practical application. Simulation results in wideband shortwave channel show that turbo code can improve the bit error rate (BER) performance compared with the traditional channel coding. Meanwhile, the system can also inhibit the channel interference and symbol interference effectively and the performance of the system is greatly improved.
