Two improved SLM methods for PAPR and BER reduction in OFDMROF systems
We proposed two methods which can reduce PAPR and BER in OFDMROF systems. Proposed ED-SLM method use EPD to detect signals without SI. Proposed SLM takes a matrix as phase sequences and superimposed on the data signals. Proposed SLM can obtain good PAPR and BER performance than traditional methods. Detail analysis about the PAPR and BER performance are shown in paper.
