Abstract :
In this paper we test an elaborated algorithm based on particle Swarm Optimization for reducing the Peak to Average Power Ratio (PAPR) with respect to ACE-AGP (Active Constellations Expansion) in OFDM signals, by removing and then rearranging pilots in the original signals. Simulation results show that the proposed method doesn´ undergo any degradation interm of PAPR reduction with a very low complexity.
