%X Methods of reducing the Peak-to-Average-Power Ratio (PAR) of the Orthogonal Frequency Dixision Multiplexing (OFDM) system have their advantages and disadvantages. In many cases, only using one of them can not achieve the desired effect of reducing or can achieve the desired effect but at the price of large performance loss on certain aspect. In view of such a situation, a joint algorithm named PTS-Clipping algorithm was given based on the complementarity between the PTS and impulse cancellation. Firstly, the algorithm used PTS to process OFDM signal to reduce PAR, then the result was further processed by impulse cancellation to further reduce PAR. As long as the two methods of reducing the PAR level were selected properly, it could reduce PAP and the computational complexity, and not have too much noise. Simulations have proved the validity of the proposed method.
