Abstract
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.
