Abstract
Description
technical field
[0001] The technical scheme of the invention relates to a multi-carrier transmission system of digital information, specifically a method for suppressing PAPR in an OFDM system based on bat algorithm. Background technique
[0002] Orthogonal Frequency Division Multiplexing (hereinafter referred to as OFDM) technology is one of the multi-carrier transmission technologies. Due to its obvious advantages such as high spectrum utilization, effective resistance to inter-symbol interference, and anti-multipath fading, it has received extensive attention in recent years. . However, due to a series of defects in the OFDM technology, it faces many difficulties and challenges in application, one of which is a relatively high peak-to-average power ratio (Peak-to-Average Power Ratio, hereinafter referred to as PAPR), referred to as peak-to-average ratio. High PAPR will distort the transmission signal, degrade the performance of the entire system and affect the efficiency...
