The device and method for producing a factor of merit of the signal to noise ratio for the coding, 1984,

摘要

The invention relates to the techniques of estimation of the signal to noise ratio of the pharmaceutical]. / p & & p & a device intended to the estimation of the signal to noise ratio of a sequence of binary data coding, 1984, in particular comprises a differentiator 26 which detected the transitions in the pharmaceutical received; means of the reference 8, 10, 16, 18, 20, which produces the reference signals having a consistency of phase relative to the instants of change of logic state of the pharmaceutical, in the source which emet the pharmaceutical, means of generation of clinical of sd 24, 30 which redistribution the transitions in the different groups as a function of their difference with respect to the instants of the change of logic state at the source, and processing means 34 which determine the signal to noise ratio of the pharmaceutical received, on the basis of clinical of sd. / p & & p & application to transmission systems of pharmaceutical.
