In this paper, we present the code design structure of unitary and non-unitary differential space-frequency group codes (DSFCs) for multiple-input multiple-output (MIMO)- orthogonal frequency division ...

Selected mapping (SLM) techniques have been used to reduce the high peak-to-average power ratio (PAR) in Orthogonal Frequency Division Multiplexing (OFDM) systems. The capacity of PAR reduction can be ...
