Simulation research and parameter optimization for a frequency-domain equalizer
Shuo Wang, Lei Liu, Xiaotao Wang · 2016
This paper proposes a new frequency-domain equalization to solve the non-linear distortion caused by the equipment's imperfection in wideband high-speed transmission systems. The method can realize the channel equalization in complex baseband with lower consumption of resources while achieving good performance. The paper gives out the principle of the frequency-domain equalization and presents the calculation of filter parameters. In addition, simulation and analysis on the factors affecting equalization performance, including filter taps, out-band data addition, linear group delay of reference channel are presented. Lastly, the simulation result demonstrates the performance and validate this proposed method.
