Three Timing Synchronization Methods Based on Two Same Preambles for OFDM Systems

摘要

The purpose of this paper is to propose two fast timing synchronization methods of OFDM System which has two preamble symbols, the two preamble symbols are used for SNR estimation for OFDM systems. The synchronization techniques are examined in Multipath fading environments for comparison. The results of the performance comparison are presented in terms of mean obtained by simulations.
