Cavallaro, "Post-Compensation of RF Non-Linearity in Mobile OFDM Systems by Estimation of Memory-less Polynomial," vol. 1, 2002.https://hdl.handle.net/1911/19922Conference PaperThe high peak-to-average-power-ratio (PAPR) of OFDM systems introduces inevitable non-linear distortion in the transmitter and causes both in-band distortion and out-of-band spectrum re-growth. In this paper we propose a novel scheme to compensate for the non-linearity of RF transmitters with solid-state-power-amplifiers (SSPA) in OFDM by Least Square (LS) estimation of the nonlinear parameters modeled by memory-less polynomials. The compensation is easily achieved by subtracting the higher-order polynomials of the input from the RF output. Simulation results for spectrum masking as well as the BER curve in 16-QAM OFDM show very stable and promising performance as well as simple implementation.engPost-compensationNon-linearityOFDMRFPAPRConference paperPost-compensationNon-linearityOFDMRFPAPRhttp://dx.doi.org/10.1109/ISCAS.2002.1009816
