  • High data transmission rates and high mobility give rise to time selectivity and frequency selectivity in wireless communication channels. This paper investigates Multi-Input Multi-Output (MIMO) time and frequency doubly selective channel estimation using polynomial interpolation method for data block transmissions. Firstly, a polynomial interpolation model is introduced to represent doubly selective MIMO channel; then, relying on channel Doppler fading rate and the polynomial error term, the polynomial model order and the length of the whole data block are obtained; Finally, based on polynomial interpolation channel model, MIMO doubly selective channels are estimated using pilot symbol assisted modulation. Simulation results show that the proposed estimation method has effective performance.
