%X An OFDM system with 16DAPSK modulation for each subcarrier is considered. In this paper, a novel bit soft-output demodulation decoding scheme which is simpler to implement for coded 16DAPSK signal is proposed and investigated. The simulation results show that about 1.2dB performance gain can be achieved in AWGN, flat Rayleigh fading, and multipath Rayleigh fading channels with forward error correct coding (rate 3/4, punctured convolutional coding) compared with hard-decision decoding. The Bit-Error-Rate (BER) will be reduced if this method is applied in 100Mbps 16DAPSK-OFDM millimeter-wave broadband mobile access experimental system developed by CRL in Japan.
