Abstract：
The International Telecommunication Union (ITU) has already defined the requirements for the next generation of mobile communications, 6G. Among other constraints, the increased use of higher frequencies and the need for ubiquitous communications challenge the operation of Orthogonal Frequency Division Multiplexing (OFDM) under powerful non-linear amplification. Indeed, the high peak to average power ratio (PAPR) of OFDM leads to severe performance degradation when signals go through nonlinear power amplifiers. http://t.cn/AXXbw3zV http://t.cn/AXXbw376
