OPTIMIZATION OF GROUP SIGNAL PARAMETERS OF GENERAL CLASS ORTHOGONAL HARMONIC SIGNALS TRANSMISSION SYSTEMS

Abstract

In the article the modeling of ADSL2+ technology transmission system over ТПП-0,5 type telephone cable using generic class orthogonal harmonic signals with different values of guard intervals is provided. The dependence of the interference noises from the line parameters to the extent that the value of the guard interval with an improved algorithm for calculating the ratio of the effective values of the interference noise and signal is investigated. Achievable transmission rate of generic class orthogonal harmonic signals transmission systems over ТПП type telephone cable considering the value of the guard interval and the power of additive noises is estimated.
