Abstract
In this paper, the sampling frequency synchronization for OFDM systems is modeled as a frequency recovery loop, and how the noise component of the frequency recovery loop affects on the symbol synchronization is analyzed. Both the theoretical analyses and numeric simulation show the symbol synchronization is necessary for the coherent detection in an OFDM system because even small noise component in the frequency recovery loop will lead to large FFT window drift.
