一般注記This TD presents an iterative spatial demapping(ISM) for simultaneous full data exchange in three-way relaying systems where there is no direct link between the users. Based on a priori knowledge provided by the decoders、 ISM demapper makes it possible for the three users to exchange information simultaneously within only two phase transmissions by help of a relay. In the first phase、 each user transmit simultaneously、 while at the second phase、 the relay amplify-and-forward thereceived composite signals to each user. The performances are evaluated by computer simulations in additive white Gaussian noise (AWGN) and frequency-flat Rayleigh fading channels. Bit-error-rate (BER) performance results show that clear turbo cliff is achieved at each user’s transmit power of 2.38 dB in AWGN channel (for each user). Extrinsic information transfer (EXIT) chart-based analysis are also presented to evaluate the convergence property of the iterative decoding algorithm. The proposed structure is simple since each transmitter consists of 2-state rate-1 doped accumulator as an inner encoder and short memory convolutional code (CC) as the outer encoder. Since theproposed technique is also spectrally efficient (because only two phase transmission is used for three users)、 its application application includes future conferencing multi-way relaying systems where energy and computational complexity are of significant important.
