Time and Frequency Synchronization Techniques for OFDM Systems operating in Gaussian and Fading Channels: A Tutorial The aim of this paper is to survey and compare previous methods for Data-aided timing and frequency synchronization of O

Frequency Synchronization in OFDM System An accurate frequency synchronization method using the zadoff-chu (ZC) constant envelop preamble is analyzed, and a new preamble weighted by pseudo-noise sequence is used for orthogonal frequency division mu
