Steepest Descent Multimodulus Algorithm for Blind Signal Retrieval in QAM Systems
Shafayat Abrar · arXiv (Cornell University) · 2017
We present steepest descent (SD) implementation of multimodulus algorithm (MMA2-2) for blind signal retrieval in digital communication systems. In comparison to stochastic approximate (gradient descent) realization, the proposed SD implementation of MMA2-2 equalizer mitigates inter-symbol interference with relatively smooth convergence and superior steady-state performance.
