BPSK-SLM for reducing PAPR

I want simple and easy code for reducing PAPR by using SLM scheme with OFDM. Try first to get BPSK-ODM and then apply SLM to it to see how much differences between with and with out SLM, be careful with how to select the best phase or the way you use the phase, command every single line and will be discussion after you done the code. be faster and accurate please .
