论文摘要
在本文中，使用系统设计的，多重的代码字矩阵改善了基于置换调制的多个输入多重输出（MIMO）可见光通信的光谱效率。然后为接收器设计了软性决定，低复杂性检测方案，并将其与最大似然（ML）检测方法进行比较。位错误率（BER）结果显示，软确定检测算法能够在不了解通道状态信息的情况下解码传输信息。这使移动接收器在发射机单元的视野内分解信息。 BER结果还显示了与某些代码手册中ML检测的密切匹配，并且在室内环境中，对接收器的不同位置进行了软否决解码器的性能。
In this paper, the spectral efficiency of permutation modulation-based multiple input multiple output (MIMO) visible light communication is improved using systematically designed, multiweight codeword matrices. Soft-decision, low-complexity detection schemes are then designed for the receiver and compared with the maximum likelihood (ML) detection method. Bit error rate (BER) results show the soft-decision detection algorithm is able to decode the transmitted information without knowledge of the channel state information. This enables the mobile receiver decode information while within the field of view of the transmitter unit. The BER results also show a close match with the ML detection in some codebooks and the performance of the soft-decision decoder is evaluated for different positions of the receiver in an indoor environment.
