Abstract:
PCT No. PCT/NL92/00039 Sec. 371 Date Aug. 23, 1993 Sec. 102(e) Date Aug. 23, 1993 PCT Filed Feb. 27, 1992 PCT Pub. No. WO92/16063 PCT Pub. Date Sep. 17, 1992System for broadcasting and receiving digital data within time divisional multiplexed channels, grouped in frames, each frame comprising multicarrier symbols, including data symbols and system symbols, each symbol comprising a set of orthogonal frequency division multiplexed carriers at carrier positions within a frequency raster with regular carrier spacing. To provide in such system the possibility for a dynamic and accurate synchronization of the local oscillator of the receiver with that of the transmitter while allowing the free running tolerance range of the receiver's local oscillator to be much wider than that of the known receiver, the frames include frequency reference symbols, each carrying information to generate a peak value at at least one reference peak position within the frequency raster separated by at least one carrier position from each of the edges of the frequency raster and by at least two carrier positions from an eventual subsequent reference peak position.
