A study on frame synchronization method for adaptive array antenna

DOI

説明

This paper proposes a reference signal synchronization method for improving the performance of the maximum likelihood type synchronization method under the realistic environment accompanying frequency offset. In the proposed method, the search of correlation was carried out to not only the timing direction but also frequency offset direction. In this way, correlations were computed for time and frequency direction and two dimensional maximum correlation search has been done. In this way the reference signal synchronization has been achieved. Furthermore, a increase ratio of the computational complexity for the conventional method has been shown. We have made it clear that the increase is relatively small and this ratio decreases with increasing the number of antenna elements
