Abstract

In Orthogonal Frequency Division Multiplexing (OFDM) used in Wireless Sensor Network (WSN), in order to restrain the intermodulation interference between subcarrier and out-of-band radiation brought by system nonlinearity of Peak-to-Average Ratio (PAPR), a kind of joint algorithm is put forward, which is based on Selective Mapping (SLM) and Repeated Clipping and Filtering (RCF). By theoretical analysis, the joint scheme applied in OFDM system can reduce the PAPR dramatically. Further, simulation result afterwards verifies the effectiveness of the method, which can avoid Bit Error Rate (BER) performance degradation. So the method proposed in the paper proves to be very effective.
