People have been looking for TWDP fading ever since the distribution was published in 1999. Taken from the Wikipedia page on TWDP fading:
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.
The TWDP fading model was formulated back at Virginia Tech while I was a graduate student, eventually published in IEEE Transactions on Communications. Since then, researchers have found TWDP fading in airplane fuselages, forests, mm-wave microcells, and university RF labs. Where will this fading show up next?
