Abstract:In this paper, the mathematical model of QAM two dimensional digital communication system based on the Codex 9600 modem is given. By using the Volterra kernel, the quantitative analysis of linear and nonlinear intersymbol interference at the output of the orthogonal modulators due to the nonlinear telephone channel having memory is presented when the high speed data signal is transmitted in this system.
Keywords:Telephone Communication System  Digital Communication System  Intersymbol interferences
