Title:
SYNCHRO-FRAME METHOD BASED ON THE DISCRETE LOGARITHM
Document Type and Number:
WIPO Patent Application WO/2009/071589
Kind Code:
A3
Abstract:
Method for transmitting data having a first format or format 1 in a datastream complying with a second format, the second format or format 2 consisting of a stream of data symbols incorporating in a regular manner a symbol dedicated to synchronization and placed every r data symbols, the symbol dedicated to synchronization being the current term of a series S(t) satisfying a linear recurrence, the data being split in format 1 into data blocks of fixed size including kr symbols, the data symbols being considered to be elements of a finite field GF(q) where q is the number of elements of the field, the series S(t) satisfies a linear recurrence over GF(q) and admits as characteristic polynomial a primitive polynomial P of degree n over GF(q), and is periodic with a period T=qn-1, α being a root of P in the field GF(qn).
