摘要

Swarm intelligence algorithms are applied to suppressing peak to average power ratio (PAPR) in CO-OFDM system by optimizing phase of subcarriers. The result shows that all of these algorithms can effectively reduce PAPR, and the PAPR of CSO optimized signal is reduced by 1.5dB, 0.77dB and 0.28dB compared with that of PSO, BSA and BA optimized signals.
