ABSTRACT:
Receiver and transmission system for orthogonal frequency-division multiplexing signals comprising a frequency synchronization circuit (116) which has a local oscillator (214) whose frequency is controlled by a correction signal .epsilon.. The latter is generated by a frequency detector (213) which operates in the time domain, by utilizing the redundant information contained in such signals. The performance of the invention is particularly of interest for transmissions on multipath channels which occur in mobile radio, digital television, and so on.
