A hybrid RTS-BP algorithm for improved detection of large-MIMO M-QAM signals
2011
2011 National Conference on Communications (NCC)
Low-complexity near-optimal detection of large-MI-MO 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: ) Although RTS achieved close to optimal performance for 4-QAM in large dimensions,
