Summary

[edit]
Description

Plot of the performance of several modulation techniques against the SNR. The calculations were made using an Octave source (but works on Matlab as well), the plot was made using Gnuplot. Here are two helper functions:

 
The SVG code is valid.
 
This plot was created with Gnuplot by v.

and

 
The SVG code is valid.
 
This plot was created with Gnuplot by v.

and here is the code that makes the calculations. It saves the data in a file called channel.dat:

 
The SVG code is valid.
 
This plot was created with Gnuplot by v.

The file channel.dat is used in the following Gnuplot code to get the plot:

 
The SVG code is valid.
 
This plot was created with Gnuplot by v.
that created channel.svg. Finally I have post-processed it with Inkscape and re-named it.
