Abstract:
PCT No. PCT/EP91/01847 Sec. 371 Date May 27, 1992 Sec. 102(e) Date May 27, 1992 PCT Filed Sep. 25, 1991 PCT Pub. No. WO92/06545 PCT Pub. Date Apr. 16, 1992.A device in which the frequency band (W) of a multiple carrier signal (MCS) is divided into a number K of sub-bands. The data contained in each sub-band are sampled at a predetermined rate (Sr) to generate a spaced sequence of samples. The data samples from all the sub-bands are time multiplexed to produce a composite signal comprising the K successive spaced sequences of samples. In this way, the composite signal transmits the data at a high apparent rate suitable for demodulation by a conventional multiple carrier demodulator designed for this high data transfer rate. This device is used in satellite communication systems.
