Abstract

This paper exploits the cyclic prefix to create a blind, adaptive, globally convergent channel shortening algorithm, with a complexity like LMS. The cost function is related to that of the Shortening SNR solution of Melsa et al., and simulations are provided to demonstrate the performance of the algorithm.
