In this paper, we have proposed an effective hybrid partial transmit sequence (EHPTS), which addresses the problem of peak-to-average power ratio (PAPR) in a reconfigurable high-speed multi-input, multi-output orthogonal frequency division multiplexing (RHS-MIMO-OFDM) technology and efficiency minimizes PAPR in orthogonal frequency division multiplexing (OFDM).But the PTS technique needs to analysis all the probability of phase rotation factors which results in increases of mathematical model computation complexity grows exponentially with the increase of various subcarrier and sub-blocks. To reduce the analysis complexity, we propose a method mainly operated on to select the optimized phase factors to reduce the high PAPR. The proposed RHS-MIMO-OFDM system incorporated the novel local analysis operations that are designed and implemented to explore the optimum phase factors. The results of the simulation show that the proposed EHPTS method are reduced PAPR effects on OFDM system when it compared to the conventional PTS techniques (U = 4).
