 技術摘要： |
The present invention relates to an initial synchronization apparatus assisted by inherent diversity over time-varying frequency-selective fading channels. Based on motivation from statistical derivations, the present invention provides a novel initial synchronization method for estimating timing error and carrier frequency offset (CFO) by embedding matched filters into RAKE fingers to approach modified CramerRao lower bounds (MCRLBs). In addition, the present invention is then built to approach modified CramerRao lower bounds by taking advantage of a maximum ratio combining (MRC) criterion. In practice, the proposed technique can significantly outperform a conventional initial synchronization technique on the timing error and CFO estimations over multipath fading channels.
