The aim of this study is to devise detection processes for digital modems operating at rates of 9600 bit/s and more over telephone lines, using coded QAM signals. The baseband representation of QAM systems and the signal distortion introduced by the telephone circuits are first investigated to derive a suitable model for the simulation of data transmission systems, using a digital computer.
