Concatenated Permutation Codes for Indoor MIMO Visible Light Communication
share
In this paper, concatenated permutation codewords are used to improve the data rate of permutation-aided space-time shift keying in multiple input multiple output (MIMO) visible light communication. Soft-decision 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 detect the transmitted information without knowledge of the channel state information. The BER results also show a close match with the ML detection in some codebooks.
