Abstract
Decreasing the peak‐to‐average power ratio (PAPR) is a great challenge for data communication using OFDM. Here is introduced a new hybrid optimized partial transmit sequence (PTS) for minimizing the PAPR, where data encryption is done with 4D DFT-based hyper-chaotic sequence. An innovative hybrid seagul optimization and salp swarm (HSOSS) optimization are proposed here to produce a phase weight factor for the PTS. Several sizes of the subcarrier are investigating the new approaches performance. The proposed model is implemented in MATLAB platform and performances are calculated with factors like bit error rate (BER) with respect to signal-to-noise ratio(SNR), PAPR complementary cumulative distribution function (CCDF) in regard to SNR, and the finally, based on the computation time, final results are compared.
