Iterative parameter estimation in MIMO flat-fading channels with frequency offsets

Abstract

We address the problem of frequency offset and channel estimation in multi-input multi-output (MIMO) flat-fading channels. By considering MIMO system as equivalent single-input single-output (SISO) sub-systems with multi-antenna interference, a novel iterative parameter estimation method with interference cancellation is proposed. Numerical results show that this iterative method achieves a satisfactory performance.
