JOINT ITERATIVE DETECTION AND DECODING METHOD AND DEVICE

摘要

A joint iterative detection and decoding method includes:a, determining an optional constellation point number cj corresponding with each transmitting antenna, according to the number of detection signal vectors needed by joint iterative detection, the modulation exponent number M of transmitting antennas and the number of transceiver antennas, therein, cj=2M; b, choosing ?m j=1Cj detection signal vectors which have the minimum distance to the true transmitting signal in all detection signal vectors and forming a candidate collection list, according to the optional constellation point number cj corresponding with each transmitting antenna determined in the step a; c, calculating each information bit log-likelihood ratios using MAP bit detection arithmetic, according to all detection signal vectors in the candidate collection list.
