The Desert project
Underwater network protocols.
By Nautilus at The Italian Institute of Technology
DESERT Underwater is an NS-Miracle extension to DEsign, Simulate, Emulate and Realize Test-beds for Underwater network protocols
http://nautilus.dei.unipd.it/desert-underwater
(update) Have installed Desert and underling ns2, ns-miracle, and WOSS – into a VirtualBox instance in MacOS – Was able to install and run basic simulation tests but I haven’t a clue what the data actually means.

Signal processing with radio
- unintended interactions
- using the wrong tools
- measuring the invisible
- antennas
- propagation is frequency dependent
- Extreme frequencies, negative frequencies?

Demodulation of signals in Max
These patches are works in progress. Please contact me if you have questions about how they work.
- Modem.maxpat – modulation/demodulation
- gen-fm-detector2.maxpat – a phase locked loop in gen~. Use with modem.maxpat – but turn FM modulation level down to about 250.
- pid-mrmapes2.maxpat – Using a PID controller to control oscillators
Frequencies and modes
- Arduino transmitter: AM 1330 kHz.
