Modelling a Digital Communication System using Matlab

I modelled the digital communication system by a simple script. In first, if you haven't installed Matlab in your system yet, you can see my article about installation of matlab on Linux.
A digital telephone converts an analog signal(our voice) to a digital signal before transmission. While the analog signal takes on real number values, the digital signal takes on only a finite set of integer values. We can model these implementation effects and save memory by storing the digital as an integer data type rather than as type double. I did this by writing the script in the following. When I run I got the pics showing the script is nicely working in the below of the script..
