Abstract
Synchronization circuits are provided for orthogonal frequency division multiplexing (OFDM) receivers. The synchronization circuits include a fast Fourier transform (FFT) processor and a synchronization unit. The FFT processor is configured to perform FFT of an input signal. The synchronization unit is configured to obtain a channel impulse response (CIR) using an output signal of the FFT processor and relocate an FFT window based on the CIR. Related receivers, methods and computer program products are also provided.
