Abstract

The MIMO-OFDM channel estimation method is researched based on the system design, and a space-frequency domain optimal pilot-tones design algorithm is presented. The algorithm unique capability of estimating fast time-varying and frequency-selective fading channels, and the simplicity of its least square (LS) algorithm free of matrix inversion, so as to greatly decrease the complexity. The computer simulation proves that the algorithm achieves optimal channel estimation in the sense of obtaining the minimum mean square error (MSE) of channel estimation.
