In this paper, the authors have proposed a simple but effective way of improving the performance of channel estimation for MIMO SCBT systems. The proposed channel estimation method utilizes the property that the shift of the pilot signal can also be utilized to identify the channel information as a new pilot. Regardless of the Signal-to-Noise Ratio (SNR) and the pilot type, the proposed method can achieve about a 1.72 dB performance gain in term of the MSE of channel estimation for each antenna branch.
