In this paper, we address methods of mitigating one of the major issues affecting wireless
location accuracy in land mobile terrestrial environments: nonline-of-sight (NLOS) …

Image similarity or distortion assessment is fundamental to a wide range of applications
throughout the field of image processing and computer vision. Many image similarity …

We present a geometrical and time-variant wireless vector channel model with
hyperbolically distributed scatterers for a macrocell mobile environment. This model is …

In this paper we present a geometric multipath propagation model for a microcell mobile
environment. The proposed model provides the statistics for the direction-of-arrival (DOA) of …

In this study, the authors investigate geometrically based statistical channel models for
outdoor and indoor propagation environments. These models idealise the scatterers laying …

In this study, two techniques are introduced for image steganography in the spatial domain.
These systems employ chaos theory to track the addresses of shuffled bits in …

A geometric scattering model that predicts the actual measured probability density functions
(pdf's) for the direction-of-arrival (DOA) and time-of-arrival (TOA) is highly desirable …

One of the fundamental research areas in wireless communications is the development of
realistic models that can efficiently and accurately describe the wireless propagation …

针对频率非选择性无线多径衰落信道, 基于室外通信环境下的空心圆模型,
提出了一种改进的适应于室内通信环境的空心圆模型. 通过推导接收信号的空时联合分布以及 …

Space-time geometrical channel models proved to be of significance in wireless
communications as they provide spatial information (ie DOA, TOA) by which the …
