%X A short-wave FH/OFDM system based on joint iterative demodulation and decoding is proposed. By combining the advantage of NSD technique and iterative demodulation and decoding, the method could compensate the SNR loss caused by differential detection and improve the reliability of short-wave communication system. Numeric simulation results show that the proposed method could effectively improve the system BER performance, while it reachs to 10-5 when SNR is 5.5 dB and data rate reachs to 8.192 kbps. Joint iterative demodulation and decoding is a practical algorithm for FH/OFDM systems.
