摘要： A technology for modulating and demodulating a burst signal in a return link of a satellite system, in which the burst signal is modulated and transmitted from a transmission end of the return link and a symbol of the burst signal is identified and demodulated at a receiving end. The method includes estimating symbol timing of a burst received through the return link and synchronizing the estimated symbol timing of the burst to reference symbol timing; synchronizing a location of the timing-synchronized burst having the symbol timing synchronized to a location of a reference burst using a preamble symbol and a post-amble symbol of the timing-synchronized burst; and recovering a carrier of the location-synchronized burst whose location has been synchronized to the location of the reference burst using a pilot symbol of the location-synchronized burst.

摘要： A receiving method for a digital stream, the stream including frames having each a body composed of a variable number c of symbols and preceded by a header including d symbols, a field composed of a fixed number e of symbols unknown to the receiver and defining the number c. A locking phase of the receiving method includes receiving a series of e symbols of the stream; performing a correlation computation for pairs of symbols received, the correlation computation being used to verify a predefined relationship if the e symbols form the unknown field; determining a correlation level and determining whether the e symbols form the unknown field on the basis of the correlation level; repeating the steps until it is determined that the e symbols form the unknown field.
