Moreover, a modification with Walsh-Hadamard coding to the new model is also propsed to create multiple uncorrelated fading envelops.曾炫元中原大學中原大學電機工程研究所學位論文
Results: Regulated by RF and VF processing, the distributions of MEUS obeyed the Nakagami statistical model. The Nakagami-fitted correlation coefficient was 0.996 卤 0.003 (p < 0.05 in the t-test and p < 0.001 in the Kolmogorov-Smirnov test). Among each of the m-coded MEUS methods, the ...
(EH) model is considered. We first approximate the harvested power as a Gamma Random Variable (RV) via the Moment Matching (MM) technique. This allows us to derive analytical expressions for Outage Probability (OP) and ergodic rate (ER) that are simple to compute yet accurate for a wide ...
A scintillation signal model and a GPSAVAAS receiver model are developed. The scintillation signal model is based on a Nakagami-m distribution for intensity and a Gaussian distribution with zero mean for phase. The GPWWAAS receiver model... C Hegarty,M. El‐Arini,T Kim,... 被引量: 4发表...
In continuation with these innovations, present study was conducted to test the adequacy of two-parameter Nakagami-m distribution to derive the GIUH along with two-parameter logistic, two-parameter Weibull, and two-parameter gamma distributions (Nash model). Nakagami-m distribution approach was first...
In this paper, we discuss physical model based method to generate channel coefficients for Nakagami-m distribution. We consider the phase envelope joint distribution so that the phase of the faded signal is also considered. Mainly, the coefficients are generated by exploring the physical model that...
