Least-Squares Design of Chromatic Dispersion Compensation FIR Filters Realized with Overlap-Save Processing
Oscar Gustafsson, Cheolyong Bae, Håkan Johansson · arXiv (Cornell University) · 2023
A design method for chromatic dispersion compensation filters realized using overlap-save processing in the frequency domain is proposed. Based on the idea to use the values that are normally zero-padded, better results than using optimal time-domain design are obtained without any modification of the overlap-save processing complexity.
