Shift-and-Add Realization Trade-Offs for Chromatic Dispersion Compensation FIR Filters
Oscar Gustafsson, Cheolyong Bae · Optica Advanced Photonics Congress 2022 · 2022
Approaches to shift-and-add realization of time-domain chromatic dispersion compensation FIR filters are considered. The coefficient word length has larger impact than filter length on both BER penalty and adder complexity.
