PAPR Reduction Analysis of OFDM Systems Using GA-, PSO-, and ABC-Based PTS Techniques

The major drawback of OFDM systems is the high peak-to-average power ratio of the transmitted signal. The paper describes the PAPR reduction and some of the important PTS-based optimization techniques for the reduction of various factors of complexity comprising computational, time, and space complexity, thus making the system more optimized. The algorithms include Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Artificial Bee Colony (ABC), and Biogeography-Based Optimization (BBO). A comparison between these optimization techniques is done. Also, PTS method and the difficulty of PAPR in OFDM systems are briefly described.
