High performance and low complexity detectors are of great importance for MIMO systems, especially large MIMO systems, where there could be tens or hundreds of antennas. In this paper, we propose a layered factor graph based joint detection and decoding algorithm for LDPC coded large MIMO system. The joint factor graph which combines both detection and decoding is adopted, and Gaussian approximation is used to reduce the complexity. In the proposed algorithm, different from existing algorithms… CONTINUE READING
