摘要：
The tracking of time-varying channel is crucial for MIMO-OFDM wireless communication systems. In this paper aiming at the double-selective fading MIMO channels, a novel pilot pattern and the according adaptive channel tracking algorithm are presented. Compared with the traditional pilot patterns, the new pattern has higher frequency efficiency and is more suitable for large transmit arrays. The computation complexity, frequency efficiency and BER performance of the system assisted by the proposed channel tracking scheme are analyzed. Simulation results demonstrate that the proposed scheme can track the time varying channel effectively.
