Crest factor reduction for TD-LTE base station
2016 IEEE Information Technology, Networking, Electronic and Automation Control Conference, 2016TD-LTE system used orthogonal frequency division multiplex (OFDM) transmission scheme. OFDM is a promising multicarrier modulation technique for high-speed communications [1], However, a major drawback of OFDM signals is their high peak-to-average power ratio (PAPR).
