In this paper, we investigate the performance of the multi-input-multi-output (MIMO) relaying scheme, which combines the Alamouti code with fixed decode-and-forward (DF) protocol. Based on the relationship between the overall signal-to-noise ratio (SNR) of the system and that of the weakest hop, the closed-form expressions of outage probability and bit error probability for MPSK are derived. The analysis...
With the rapidly development of beyond third generation mobile communication system, how to improve the spectrum efficiency becomes a key problem. Based on the analysis of the quality of iterative decoding influenced by constellation labeling, a new general mapping rules was proposed in bit interleaved coded modulation and iterative decoding. On the one hand, to improve the performance of the system...
