Abstract
Receiver (RCV) adapted for compensating for Symbol Timing Offset when receiving OFDM symbols, over a communication channel (TC), comprising: means (REG, DFT, CMP) for detecting a first phase with no Inter-Symbol Interference, means (REG, DFT, CMP) for detecting a second phase with presence of Inter-Symbol Interference, means (REG, DFT, CMP) for compensating for said Symbol Timing Offset by estimating starting points of said received OFDM symbols as being one sample before the start of said second phase. The timing synchronization is achieved in frequency domain by monitoring amplitude variation of the demodulated subcarriers symbols, said variation being due to the presence of Inter Symbol Interference when the FFT window overlaps with the subsequent OFDM symbol.
