Analysis of energy detection of unknown signals under Beckmann fading channels
The Beckmann fading is a general multipath fading model which includes Rice, Hoyt and Rayleigh fading as particular cases. However, the generality of the Beckmann fading also implies a significant increased mathematical ... -
Asymptotically Exact Approximations for the Symmetric Difference of Generalized Marcum-Q Functions
López-Martínez, Francisco Javier; Romero-Jerez, Juan Manuel; López-Martínez, Francisco Javier (IEEE, 2015)
In this paper, we derive two simple and asymptotically exact approximations for the function defined as ΔQm(a, b) =Δ Qm(a, b) - Qm(b, a). The generalized Marcum Q-function Qm(a, b) appears in many scenarios in communications ... -
