The least-mean-squares (LMS) algorithm which updates the filter coefficients by a stochastic gradient descent approach is the most popular adaptive filtering one. In this paper we propose a novel amplitude banded (AB) technique with LMS on Godard (ABGodard) and Sato (ABSato) algorithms for the equalization of communication channels. The non-linear properties of the AB technique with LMS algorit...

Scientists, I once heard, have an easier time of it than composers and artists. In a ‘‘new’’ field, such as molecular biology, anything that happened more than three weeks ago is ancient history (as Sidney Brenner once said). We bold scientific searchers, like born agains, rise each morning to fashion a new world, with our own discoveries in the form of facts, lots of them (check out the length...

We propose and experimentally demonstrate a dual-polarization (DP) transceiver imbalance monitoring scheme, which is applicable for the coherent system using square QAM signals. The scheme can separate/monitor various kinds of imbalances has technical advantages multi-dimension, wide range, modulation-format-transparency. In proposed polarization scrambler configured between transmitter (Tx) re...
