Patent FR-2660133-A1 (FR)
Title: Method of scrambling, of unscrambling and of searching for synchronisation in a binary train and circuit for implementing this method
Inventor: ARTHUR ORIGHONI JEAN-CLAUDE LU
IPC: H04L7/04
Filed: 1990-03-21
Abstract: The invention relates to a method and a device for unscrambling a train of binary data. The binary train to be transmitted (TBT) consists of fixed-length (L) words (MB), in which one of the fixed-position (F) elements has a fixed value (0). It is scrambled with a fixed-length pseudo-random binary sequence (SBPA) (PRBS), and transmitted. The received train (TBER) is unscrambled with the aid of an identical pseudo-random sequence. Each element of the first word received (MB1) is compared with the element of the same rank of the second word received (MB2). The elements are selected which, in the words received, occupy the same rank and have the same fixed value (0) of the fixed-position (F) binary element, and the said comparison is continued until only one single selected element remains, which is therefore the fixed-position element (F) sought. The invention can be used, in particular, in data transmission systems.
