Two-Wave with Diffuse Power or TWDP is a model for predicting fading, an effect in radio propagation that causes a signal to be strengthened or weakened at certain locations or times. TWDP models fading due to the interference of two strong radio signals and numerous smaller, diffuse signals.
A look back at the infamous cow-head article. I wrote this because, at the time, I was getting tired of being asked about whether or not cell phones caused cancer. Interestingly, no one asks that anymore. I think people finally realized that the handset-induced car accidents were far more dangerous.

It helps to fight off the biyo biyo, which roughly translates into English as jiggling belly lard. [Read more…]
In 2004, we ran our first curated virtual space mission for Georgia Tech’s graduate-level ECE 6390, Satellite Communications. The project was entitled “Deep-Penetrating Neptune Probes” and involved a hypothetical planetary NASA mission to the gas giant Neptune to study the atmospheric composition of the gas giant. Originally suggested by Prof. Steffes (like many of the curated virtual space missions that followed), the project page archive can be found here.
