Abstract: Orthogonal frequency division multiplexing (OFDM) has the following benefits: excessive records fees and dependable transmission over fading channels. A significant disadvantage is the fact that it has an excessive peak-to-average strength ratio (PAPR). Numerous algorithms had been created to minimise the PAPR, every with its very own blessings and drawbacks. The Gaussian Firefly technique and the partial transmit sequence (PTS) are of the best algorithms. The Gaussian Firefly method can be used on this task to reduce PAPR. This approach makes use of swarm intelligence to tune the segment vectors so that you can decorate PAPR performance. As compared to current approaches, the suggested Firefly algorithm-based total PTS (FF-PTS) is a good way to obtain enhanced PAPR characteristics for OFDM signals.
