Objectives: Using the imperialist competitive algorithm (ICA) for finding the optimal values of the phase in PTS method in order to Peak-to-average power ratio reduction.
Methods/Analysis: In order to PAPR reduction we have used a numerical method to calculate the Bose–Einstein equations that appear in efficiency of solar cells.
Findings: The proposed method reduces the PAPR more than other methods and also does not lead to an increase in BER. PAPR is reduced the amount of 3.97 dB that is equal to 34.75% of initial value of PAPR. Also by increasing the subcarrier amount of these reductions are increased but required to increasing in compute the increase and cost. Novelty of the Study: For the first time, imperialist competitive algorithm (ICA) is used for finding the optimal values of the phase in Partial Transmit Sequence (PTS) method.
Conclusion/Application: One of the most important applications of the results of this study is the satellite communication system. Also, PAPR reduction will be reduced operating costs dramatically.
