Orthogonal Frequency Division Multiplexing (OFDM)

systems are more sensitive to timing and frequency offsets than

single carrier systems. This Paper presents a method of joint time

and frequency synchronization for OFDM systems. The

synchronization technique is examined in both AWGN and

multipath fading environments. Compared with conventional

schemes, the proposed schemes can achieve smaller mean and mean

square error (MSE) obtained by simulations.
