ABSTRACT:
Receiver (105) for signals transmitted according to an orthogonal frequency division multiplexing technique with carriers distributed symmetrically around a centre frequency f.sub.e, said receiver comprising a frequency synchronizer (116) for the local oscillator (214). The synchronizer (116) utilizes the fact that part of the side carriers are not transmitted to ensure in the lock-on mode a frequency synchronization having a wide lock-on range. It may also be used in the permanent mode with very little jitter. The receiver can be used in digital television for receiving signals transmitted according to an orthogonal frequency division multiplexing technique.
