Frequency Synchronization

One of the main drawbacks of OFDM is its sensitivity to carrier frequency offset. The effect of carrier frequency error on SNR was introduced in Chapter 1, where the main differences between multicarrier and singlecarrier systems were discussed. The degradation is caused by two main phenomena: reduction of amplitude of the desired subcarrier and ICI caused by neighboring carriers. The amplitude loss occurs because the desired subcarrier is no longer sampled at the peak of the sinc-function of DFT. The sinc-function is defined as sinc .Adjacent carriers cause interference, because they are not sampled at the zero-crossings ...
