Maximal Minimum Hamming Distance Codes for Embedding SI in a Data based BSLM Scheme for PAPR Reduction in OFDM

open access: yesInternational Journal of Technology, 2021
The bi-orthogonal codes for embedding Side-Information (SI) in data-based blind SLM (BSLM) proposed in Joo et al. (2012) produce better bit error rate (BER) and SI error rate (SIER) performance compared to binary codes.
