INVESTIGATION OF INTERFERENCE NOISES IN CHANNELS OF TRANSMISSION SYSTEMS BY VDSL2 + TECHNOLOGY
The paper presents the results of the interference noises research in transmission systems (TS) by VDSL2 technology when working on “twisted pair” cables. The research was carried out by analytical modeling of VDSL2-systems with frequency plan B8-6 [998-M2x-B] on UTP Cat.5e 4x0.5 cable using traditional orthogonal harmonic signals (OHS) and generalized class orthogonal harmonic signals of (GC OHS). The values of interference noise were evaluated in relative values as a percentage of the effective values of interference noise/signal.
