Abstract :
The paper relates on experiments in deriving models for satellite link channels in the Ka band using nonlinear deterministic chaos equations. The trajectories of Lorenz attractors are sampled at suitable time rates and combined to obtain attenuation samples of the fading channel, following procedures suggested by previous experience in modeling the behavior of time error series in digital communication channels. Optimization cost function structures are discussed
