In view of the correlation function matrix, a 3D atmospheric turbulence field based on the Von Karman model is generated with the Monte Carlo simulation, which realizes the deduction and application of the complex Von Karman model. The ability of the simulation to approach the theoretical result is unlimited. The whitening degree of the random number sequence and the precision and efficiency of the...
High-altitude platforms (HAPs) are considered as an alternative technology for next generation broadband wireless communications. This paper proposes three- dimensional (3-D) sum-of-sinusoids (SoS) simulation models for wideband HAP multiple-input-multiple- output (MIMO) channels. The starting point of the design procedure is a non-realizable reference model. The performance of the proposed models...
The random electromagnetic field within a reverberation chamber is modeled using a superposition of plane waves. Based on rigorous sampling theory, the ideal continuous plane-wave spectrum within the chamber is sampled over the sphere to yield nearly ideal field statistics (including spatial autocorrelation) over a specified test volume such as that occupied by an equipment under test (EUT). The same...
Estimation of the packet loss for a video transmission over a communication network is an important step for assessing the QoS perceived by the users. The loss probability is particularly important, but also the characteristics of the loss periods have a significant effect, since bursty losses influence the perceived QoS in a different way than uniformly distributed losses. In this paper, the video...
This paper studies the possibility of distinguishing between benign and malignant masses by exploiting the morphology-dependent temporal and spectral characteristics of their microwave backscatter response in ultra-wideband breast cancer detection. The spiculated border profiles of 2-D breast masses are generated by modifying the baseline elliptical rings based upon the irregularity of their peripheries...
