Efficient adaptive filtering techniques using hybrid RLS-LMS algorithm for channel equalization in optical few-mode fiber communication systems

摘要

A joint coding scheme is purposed that can achieve 48.2% enhanced convergence speed with only 16.2% more increase in hardware complexity over the conventional least mean squares algorithm for the frequency domain multiple-input multiple-output equalization in a 1000 km six-mode spatial-division multiplexed transmission system.
