Abstract In this paper, a new frequency-domain DAPSK+OFDM is proposed. Its modulation and demodulation are discussed, and its BER performance is analysed in AWGN channel. In the case f the typical AM channel, the simulation results indicate that the BER performance of frequency-domain DAPSK+OFDM is better than that of time-domain DAPSK+OFDM in Short Wave (SW) channel but poorer in Medium Wave (MW) channel. In short, it is reasonable to use frequency-domain DAPSK+OFDM in SW channel and time-domain DAPSK+OFDM in MW and Long Wave (LW) channel.
