The Simulation Design of MATLAB Applied to the Modem Technology of Digital Communication System

In order to establish a platform for the study of actual digital communication system(DCS), we often need to resort to the software Matlab installed on the compute by means of programming, modeling and simulation technology to realize the simulation of the DCS used in the real life, and use an intuitionistic interface to represent the simulation process and result, providing accurate and reliable data for related scientific study. Generally speaking, it is necessary to have an in-depth knowledge about the actual DCS before the specific simulation, decomposing it into several important components and analyzing them in details. After that, we can apply the MATLAB programming method to edit simulation program, and apply its function of modeling and simulating to establish a systemic simulation block diagram of digital communication.
