Method for transmitting useful information between two terminals and method for generating an association table used in the context of the transmission

摘要

A method for transmitting useful information between a transmitting terminal and a receiving terminal connected via a transmission channel. The transmitting terminal defines control information for the useful information, and searches in an association table, which is accessible from the transmitting terminal, for a frame-synchronization word associated with the control information. The transmitting terminal generates a frame of data from the useful information, and transmits, over the transmission channel, a data stream that includes the frame-synchronization word and the frame of data.

1. A method for generating an association table between frame synchronization words and control information items, comprising the steps of:
defining all possible control information items; defining a set of frame synchronization words according to a number of possible control information items by:
defining a length L of the frame synchronization word according to the number of possible control information items such that the length L is sufficient to distinguish all the possible control information items;listing a set of permutations of a word of the length L to obtain a set of raw words; andfiltering the set of raw words to obtain the set of frame synchronization words; and associating, with each possible control information item, a frame synchronization word in the set of frame synchronization words.
