As large amount of computations are not only needed when the conventional Selected Mapping(SLM) technique is used for reducing OFDM system PAPR
but also the effective transmission efficiency is reduced because it is necessary to transmit the side information representing the phase sequence
we propose a linear block code-based coded-SLM algorithm both theoretical analysis and computer simulations show that although slightly poorer in reducing PAPR than the conventional SLM method
this algorithm can reduce the OFDM signal PAPR more effectively than the original OFDM technique and the transmission efficiency and reliability are also significantly improved.
