DEMODULATEUR BOARD

This COFDM Demodulator Board addresses the demand for more robust transmission links, especially running in mobile environment conditions.

This modulation is especially developed for harsh environment in video links like signal fading, echoes and trees.

This board is also suitable for any kind of network applications.
