Abstract :
A guard-interval based symbol and frequency synchronization technique with an extended observation interval of the OFDM transmission with higher level modulations is investigated for the wireless radio environments. The performance of the proposed guard-interval based symbol and frequency synchronization is evaluated by the computer simulations
