Whitepaper: Pilot-Symbol-Aided Iterative Channel Estimation for OFDM-Based Systems

by Conservatoire National des Arts et MétiersJan 01, 2008

This paper from Conservatoire National des Arts et Metiers, proposes a pilot-symbol-aided iterative channel estimation for coded OFDM (Orthogonal Frequency Division Multiplexing)-based systems. Use the symbol APP provided by the channel decoder to form groups of virtual pilots. According to their reliabilities, combine these groups to improve the channel estimation. It also compares the proposed algorithm with the EM algorithm.
