Channel Estimation Techniques Used in OFDM System for Different Modulation Techniques: an Overview

A. B. Bambhaniya, J M Rathod

Abstract :

To recover accurate transmitted data at the receiver end, the information regarding channel state derived from channel estimation methods play a very important role in any communication system. In this paper the performance evaluation of different types of quadrature amplitude modulation (QAM) and phase shift keying modulations, Least Square (LS), Minimum mean square error(MMSE), Evolutionary Programming, PACE and DFT based channel estimation methods in Orthongonal frequency division multiplexing system for different modulation techniques in wireless communication is discussed
