With the modern increasing demand on simultaneous multimedia, voice, video, and data communication over the internet along with the growing interest in the design and development of the next wireless communication systems generation, it has become necessary to develop new transmission techniques that are able to accommodate high bit-rate wideband signals and to cope well with the multipath fading of wireless channels. In this paper proposed approach trying ro reduce BER by PTS with particle swarm optimization Index Terms-PTS,PSO,Clipping,BER,SNR.
