Abstract |
|
Orthogonal frequency division multiplexing (OFDM) is widely used multiplexing technique, it is one of the parallel transmission schemes that reduce the effect of multipath fading, but it also have a major drawback which causes saturation in power. And this problem is known as high peak to average power ratio (PAPR), High peak to average power ratio can be reduce by many techniques. The promising technique which help in reducing PAPR is partial transmits sequence (PTS), because it does not deteriorate the orthogonality of subcarrier. But in this scheme the complexity for searching the phase factor is increased with increase in number of sub blocks. In this paper, genetic algorithm have been used which reduces complexity arises during calculating phase factor in the PTS technique. |
