Successive Maximum Likelihood Estimation for Time and Frequency Synchronization

A new repetitive synchronization signal structure is proposed for wireless communication systems. A corresponding successive maximum likelihood detection algorithm that uses the proposed synchronization signals is provided. The successive maximum likelihood detection algorithm uses reliably estimated frequency offset in a successive way to refine the estimated timing offset. The performance of our approach is evaluated and compared to other existing algorithms.
