Performance analysis of GA-PTS for PAPR reduction in OFDM system

A low-complexity technique for reducing the PAPR of an OFDM system is presented which is known as partial transmit sequence (PTS). However, this scheme requires an extreme search over all combination of allowed phase factor. So, to reduce searching complexity there are different optimization algorithms. One of a novel and sub-optimal PAPR reduction approach is genetic algorithm based PTS technique which has less computational complexity than the PTS technique. In this algorithm, firstly population get initialized, then selection of chromosome are done after selection, crossover and mutation are performed for generating new population. The simulation result shows the performance of PAPR by adopting GA-PTS scheme.
