Executive Summary

In this paper, the authors propose an effective way of improving the performance of channel estimation for MIMO Single-Carrier Block Transmission (SCBT) systems. The proposed method utilizes the property that the shift of the cyclic pilot signal of each antenna branch can also be utilized to catch the channel information as a new pilot for MIMO SCBT systems. The receiver can continuously estimate the channel information by just shifting the received pilot signal. The channel estimation performance is improved by averaging all channel estimators since this averaging process can reduce the power of noise component.
