在多输入多输出（MIMO）系统中，已经提出了空分复用和空间调制（SD-SM）传输。然后，在SD-SM-MIMO中，通过使用信道排序QR分解与M算法最大似然检测（CR-QRM-MLD），尽管搜索次数很少，但误码率（BER）性能得到改善。此外，非零调制和零调制独立地用于SM传输。然而，这些组合没有被评估，例如幅移键控（ASK）。此外，也没有评估在MLD中有效的相位旋转（PR）。在本文中，我们提出了PR和ASK组合的SD-SM-MIMO。
In multiple-input multiple-output (MIMO) systems, space division multiplexing and spatial modulation (SD-SM) transmissions have been proposed. And then, in the SD-SM-MIMO, the bit error rate (BER) performance is improved by using the channel ranking QR decomposition with M-algorithm maximum likelihood detection (CR-QRM-MLD) in spite of the small number of searches. Moreover, the non-null and null modulation are utilized for the SM transmissions independently. However, these combinations are not evaluated such as the amplitude shift keying (ASK). Also, phase rotation (PR) which is the effective in the MLD is not also evaluated. In this paper, we propose the PR and ASK combination for the SD-SM-MIMO.
