Blind channel estimation for multiple antenna OFDM system subject to unknown carrier frequency offset

doi:10.1109/JSEE.2014.00082

Abstract

Abstract:

The problem of channel estimation for multiple antenna orthogonal frequency division multiplexing (OFDM) systems subject to unknown carrier frequency offset (CFO) is addressed. Multiple signal classification (MUSIC)-like algorithm, which generally has been used for direction estimation or frequency estimation, is used for channel estimation in multiple antenna OFDM systems. A reduced dimensional (RD)-MUSIC based algorithm for channel estimation is proposed in multiple antenna OFDM systems with unknown CFO. The Cram´er-Rao bound (CRB) of channel estimation in multiple antenna OFDM systems with unknown CFO is derived. The proposed algorithm has a superior performance of channel estimation compared with the Capon method and the least squares method.

Key words: channel estimation, orthogonal frequency division multiplexing (OFDM), multiple antennas, multiple signal classification (MUSIC)
