Robochameleon is a coding framework and component library for simulation and experimental analysis of optical communication systems.
The framework was designed to facilitate sharing code between researchers by articulating some standard methods and syntax for signal representation and function calls. It has been used successfully for this purpose within the DSP group at DTU for the past year, and we welcome contributions from other groups. The library includes physical models of most components found in coherent and incoherent optical communication systems, as well as standard DSP blocks.
The DSP blocks have been developed over a longer period of time and validated on real data.

That said, this software is provided "as-is" without warranty of any kind, as stated in the license.

Documentation

There is a quick start guide in powerpoint format in the doc folder. An HTML version of this file can be found [here](@ref quickstart) (link only works from the html API documentation).

To consult the documentation open:

• index.html located in the folder doc/user manual/html/

or type robohelp in the MATLAB command line.

Examples

Several examples can be found in the _setups/Demo folder
