Performance of mobile orthogonal frequency division multiplexing systems over time‐varying non‐linearities with memory

Autor: Alexander Beremiz Hilario Tacuri, José Mauro P. Fortes

Publikováno v: IET Communications. 9:1531-1538

The performance of modern communications transmitters utilising multi-carrier modulation techniques is highly sensitive to non-linear distortions arising mainly from the high-power amplifier. The increase in symbol duration makes the system more sens
