Abstract: PURPOSE: A blind SLM(Selected Mapping) method is provided to reduce encoding complexity and minimize the performance degradation of a BER(Bit Error Rate). CONSTITUTION: A transmission end selects a symbol sequence which has the smallest PAPR among OFDM carrier wave symbol sequences. The transmission end partitions the OFDM carrier wave symbol sequences into a constant period. A sectional phase is rotated according to the m-sequence which is used every OFDM carrier wave symbol sequence.
