Abstract :
In this paper a data aided frequency and symbol synchronization scheme for M-QAM OFDM signals is suggested. The phase discriminator and frequency discriminator for, respectively, the symbol and frequency synchronization loop are described. Simulation results in presence of Rayleigh multipath channel are reported
