@article{Datta2011AHR, title={A hybrid RTS-BP algorithm for improved detection of large-MIMO M-QAM signals}, author={T. Datta and N. Srinidhi and A. Chockalingam and B. S. Rajan}, journal={2011 National Conference on Communications (NCC)}, year={2011}, pages={1-5} }

Low-complexity near-optimal detection of large-MIMO signals has attracted recent research. Recently, we proposed a local neighborhood search algorithm, namely reactive tabu search (RTS) algorithm, as well as a factor-graph based belief propagation (BP) algorithm for low-complexity large-MIMO detection. The motivation for the present work arises from the following two observations on the above two algorithms: i) Although RTS achieved close to optimal performance for 4-QAM in large dimensions… CONTINUE READING
