Partial Transmit Sequence Based Cuckoo Search Optimization for Peak-to-Average Power Ratio Reduction in Orthogonal Frequency Division Multiplexing Systems
This paper considers the use of Partial Transmit Sequence (PTS) technique to reduce the Peak-to-Average Power Ratio (PAPR) of an Orthogonal Frequency Division Multiplexing (OFDM) signal in wireless communication systems. Search complexity for optimal phase vector is very high in traditional PTS (T-PTS) scheme, since it involves extensive random search over all the combinations of allowed phase vectors and increases exponentially with the number of phase vectors. In this paper, a suboptimal meta-heuristic algorithm for phase optimization based on Cuckoo Search algorithm is applied to search the optimal combination of phase vectors which provides best trade-off between the improved PAPR performance and computational complexity as compared to existing conventional T-PTS scheme for large number of sub-blocks. It enhances the accuracy and convergence rate of the conventional algorithms with very few parameters to adjust. Simulation results show that Cuckoo Search algorithm-based PTS (CS-PTS) algorithm is an efficient method to achieve significant reduction in PAPR.
