Abstract

A novel technique to recover symbol timing of OFDM systems is proposed. The proposed technique does not require cyclic prefix, pilot signals, training symbols, or any other supplementary data, this will significantly improve the system power and bandwidth efficiency. The proposed algorithm exploits the interference that results due to the loss of orthogonality between sub-carriers where the variance of the resulted interference is proportional to the offset from the optimum sampling point. The proposed technique does not require prior fine carrier synchronization and it is capable of extracting symbol timing at very low E_b/N₀ values. Theoretical and simulation results have shown that symbol timing can be recovered for E_b/N₀ as low as -3 dB, such performance is considered to be superior when it is compared to other techniques.
