Abstract(in English) | Maximum likelihood block signal detection using QR decomposition and M-algorithm (QRM-MLBD) can significantly improve the packet error rate (PER) performance of cyclic prefix-inserted single-carrier (CP-SC) multi-input multi-output (MIMO) spatial multiplexing when compared to the frequency-domain spatial filtering based on the minimum mean square error (MMSE) criterion. However, in order to achieve the sufficiently improved performance, a fairly large number M of surviving paths in the M-algorithm is required and this results in a very high computational complexity. If smaller M is used, the probability of removing the correct path at early stages increases. In this paper, to reduce this probability, we proposed a training sequence (TS)-aided QRM-MLBD for SC MIMO spatial multiplexing. We show by computer simulation that training sequence-aided SC-MIMO multiplexing (TA-SC MIMO) multiplexing using TS-aided QRM-MLBD with M=16 can achieve almost the same PER performance as CP-SC MIMO multiplexing using the conventional QRM-MLBD with M=1024 in the case of 16QAM and 4x4 MIMO spatial multiplexing. |
