Summary:
In this letter, the problem of attaining frequency synchronization for high rate WPANs is considered. An estimation of the frequency offset is essential step at the receiver because the frequency offset means that the phase of transmitted signal is corrupted. The proposed algorithm utilizes the difference in phase between received preamble and estimated preamble. It turns out that the proposed algorithm has low complexity and good performance. To enhance the capability, we use peak phase detector. The performance of the proposed algorithm is assessed by computer simulation, and the frequency offset variance is compared to Cramer Rao Bound.
