The thesis focuses on the multipath fading problem in aerial communication. At the beginning of this paper, we build the model of the aerial communication channel and complete the analysis on the esse...
Adaptive Transmission of Variable-Rate Data over a Fading Channel for Energy-Efficiency
Adaptive Transmission Variable-Rate Data Fading Channel Energy-Efficiency
2015/8/17
Adapting to a time-varying channel to maximize the average information rate for a given power constraint is a well-understood problem. Important studies (e.g., [I], [Z], [3]) have developed optimal ra...
Fading memory and the problem of approximating nonlinear operators with Volterra series
Continuous nonlinear operator volterra series operator nonlinear dynamic system
2015/8/13
Using the notion of fading memory, very strong versions of two theorems are proved. The first is that any time-invariant (TI) continuous nonlinear operator can be approximated by a Volterra series ope...
