Information Technology Journal, 2011, 10(5), 914-926.

Abstract

This study reports a detailed review on selected channel estimation algorithms for orthogonal frequency division multiplexing communication systems. Pilot based channel estimation algorithms such as least square, minimum mean square error, maximum likelihood and decision feedback estimators are discussed and also compared in terms of their simplicity, computational cost and suitability conditions. Moreover Subspace Based Blind channel estimation algorithm for cyclic prefix system is described along with its limitation of applicability for fast varying wireless channels. References for the report and other estimating algorithms which are not considered here are also cited.
