EVALUATION OF THE TRANSMISSION RATE, WHICH IS ACHIEVED BY GENERALIZED CLASS ORTHOGONAL HARMONIC SIGNALS TRANSMISSION SYSTEMS

Abstract

The using of generalized class (GC) orthogonal harmonic signals (OHS) allows to reduce interference noises in comparison with traditional OHS. Comparative analysis of achievable transmission rate of three variants of GC OHS TS and of traditional OHS TS is performed on the example of ADSL2+ technology. The comparison was done for the loss of the transmission rate of these systems with respect to variant without interference. GC OHS TS variant that provides the maximum achievable transmission rate considering interference noises is determined. Achievable transmission rate considering interference, external additive noise and crosstalk for the selected variant is defined. Possibility of GC OHS using for increasing OHS TS transmission rate is proved.
