An efficient MIMO receiver based on BP algorithm with truncated message-passing

摘要: There is a common understanding that using Multiple-Input Multiple-Output (MIMO) transmission techniques improves the capacity of wireless channels [1]. Associating MIMO with Forward Error Correction (FEC) codes efficient to achieve reliable digital transmissions. It becomes particularly appealing when scheme concatenated Low Density Parity Check (LDPC) code. A low-complexity BP-based layered detection and decoding for NB-LDPC coded system detailed. division by ten number operations in BP detector obtained negligible performance penalty compared full-complexity BP. On other hand, four ML targeting same performance. In addition observed complexity gains, greatly reduces iterative receiver latency making such solution suited hardware implementation.
