HIGH-FREQUENCY DATA TRANSMISSION SYSTEM FOR HF TRANSMISSION USING STANDARD RECEIVER RECEIVERS

摘要

A system and method for high-speed data transmissions, the data being transmitted in the form of frames composed of a preamble and data blocks, each block comprising a fixed or probe sequence and data, the system comprising at least one transmitter and a receiver, the transmitter comprises at least one means adapted to generate for a frame Tn a synchronization sequence comprising at least a first probe S1 and a second probe Sf defined from an original probe SBi of the data block Bi, and in that the probes Si, Sf thus generated have an autocorrelation substantially identical to that of the original probe.
