A MODIFIED SLM SCHEME WITH LOW COMPLEXITY FOR PAPR REDUCTION OF OFDM SYSTEMS
摘要
<p>Provided are an apparatus and method for reducing a PAPR with less computation complexity without distortion using a selected mapping scheme (SLM) in an OFDM system. The method includes: generating a plurality of OFDM signal sequences by performing an inverse fast Fourier transform (IFFT) operation on input symbol sequences, which are probabilistically independent and have identical information; linearly combining the plurality of OFDM signal sequences by using complex numbers; and generating different OFDM signal sequences based on the linear combination. Accordingly, the number of phase sequences can be increased without almost increasing a computation amount of SLM.</p>
