| Popis: | High performance and high efficiency detection scheme is one of the key issues for MIMO-LDPC system designs. In this paper, we proposed a hybrid jointed detection scheme for MIMO-LDPC detection, in which the expectation propagation (EP) algorithm is used in MIMO detection and the belief propagation (BP) algorithm is adopted for the low density parity check code (LDPC) decoding. In the proposed scheme, we provide a jointed detection algorithm (EP-BP JDD) with the integrated factor graph for MIMO-LDPC systems. Compared with conventional MMSE-PIC IDD and BP-BP JDD, the proposed method can achieve low computational complexity with high performance. The complexity and performance gains become more significant with the number of antennas increasing. |
