摘要

Mobile data traffic is expected to triple between 2018 and 2021 [1]. To meet past and future growth targets in an increasingly limited electromagnetic spectrum, wireless communications systems have evolved at a staggering rate. Current mobile phone standards like 3rd Generation Partnership Project LTE and Wi-Fi exploit orthogonal frequencydivision multiplexing (OFDM) as a means of achieving the required wireless data rates. OFDM is also a potential candidate for future 5G services. Although highly spectrally efficient, OFDM suffers from a large peak-to-average power ratio (PAPR), where the transmit signal peak envelope power can be 12 dB greater than the average value.
