Abstract:
High peak-to-average power ratio (PAPR) is one of the major drawbacks of orthogonal frequency division multiplexing (OFDM) communication system, which causes signal distortion and affects communication performance. Partial transmission sequence (PTS) is an effective method to reduce the PAPR, but it cannot adaptively select processing parameters for the signal and has high computational complexity. Aiming at the defects of PTS method, this paper propose an adaptive PTS method based on fuzzy neural network (FNN-APTS). The method considers the signal and system characteristics, combining the learning ability of the neural network with the reasoning ability of the fuzzy control method, to select the processing parameters for the signal adaptively. The simulation results show that the proposed FNN-APTS method can adapt to different OFDM models, reducing the computational complexity and improving the system performance while ensuring the reasonable PAPR.
