摘要：
This work focuses on the construction of optimized binary signaling schemes for two-sender uncoded transmission of correlated non-uniform sources over non-orthogonal Gaussian multiple access channels. Based on an error-rate analysis under joint maximum-a-posteriori decoding, optimized binary-pulsed amplitude modulation constellations for two senders are derived to minimize the system's error rate. The joint probability distribution of the two-senders' source is observed to induce a special layout of optimized constellations which can effectively control the interference due to non-orthogonal transmission. Numerical results further confirm that significant gains are achievable by the proposed design.
