Abstract

We present a software program simulating data transmission through a noisy channel. This program makes it possible to simulate simplex or full duplex transmissions of digitalized data, of any type. Through a modelization of the error rate and of the kinds of errors we can simulate transmissions, from submarine ones (error rate about 10 -2) to transmissions via satellites (error rate about 10 -5 to 10 -8). This software operates from one initial file to be transmitted, and from user-entered parameters of simulation. The final results are of two kinds: two files, and several numerical results. The two files are: The initial one transmitted without data protection, and the initial one transmitted with data protection by error correcting codes. The numerical results are: The binary experimental error rate, the binary residual error rate, and the transmission efficiency.
