Concatenated Permutation Block Codes for Space-Time Shift Keying in Indoor Visible Light Communication
share
In this paper, concatenated permutation codewordsare used to improve the code rate of permutation-aided space-time shift keying in multiple input multiple output (MIMO)visible light communication. Soft-decision detection schemes arethen designed for the receiver and compared with the maximumlikelihood (ML) detection method. Bit error rate (BER) resultsshow the soft-decision detection algorithm is able to detect thetransmitted information without knowledge of the channel stateinformation. The BER results also show a close match with theML detection in some codebooks.
