This work studies the correlation effect on a new Algebraic Carrier Frequency Offset (CFO) estimation technique for multi-input multi-output (MIMO) orthogonal frequency divisionmultiplexing (OFDM) systems employing Algebraic Space Time Coding (ASTC), in quasi-static correlated Rayleigh frequency-selective fading channels. The technique uses a preamble and is thus especially suitable for burst mode communication. The preamble consists of orthogonal training sequences simultaneously transmitted from the various transmit antennas. Index Terms — Carrier frequency offset (CFO), channel estimation, frequency offset estimation, multiple-input multiple-output (MIMO), orthogonal frequency-division multiplexing (OFDM), Algebraic Space Time Coding (ASTC).
