New non-asymptotic upper bounds on the capacity of non-coherent multiple-input multiple-output (MIMO) Gaussian fading channels with memory are proposed. These bounds are used to derive upper bounds on the fading number of regular Gaussian fading channels and on the pre-log of non-regular ones. The resulting bounds are tight in the multiple-input single-output (MISO) spatially IID Gaussian case ...

introduction: scatter radiation is one of the major sources of error in nuclear medicine data processing. different methods of scatter correction have been introduced in order to improve the quality of data. however the best method is to avoid recording of scatter photons in acquisition. the only difference between scattered and non-scattered photons is the energy. pulse height analyzer is the ...

This letter analyzes the outage probability of opportunistic amplify-and-forward relaying over asymmetric and independent but non-identically distributed (i.n.d) fading environments. The work investigates the scenarios where cooperative nodes are located at different geographical locations. As a result, the different signals are affected by different i.n.d fading channels, one may undergo Ricia...

This study compares the fading of inkjet prints tested in environmental chambers using either an electrostatic discharge or ultraviolet radiation to produce ozone. Our results indicate that over the range of 0.1 to 5.0 ppm ozone in air, very similar fading characteristics are obtained at 50% RH with the microporous and swellable polymer based inkjet papers tested, whether ozone is produced with...

A key element for many fading-compensation techniques is long-range prediction of the fading channel. A linear approach, usually used to model the time evolution of the fading process, does not perform well for long-range prediction. In this article, we propose an adaptive channel prediction algorithm using a state-space approach for the fading process based on the sum-sinusoidal model. Our sim...

This paper represents the MIMO channel capacity over Rician fading, Rayleigh fading and Nakagami fading channel. Here Rician fading model employs a zero-mean stochastic sinusoid as the line-of-sight component. This paper offers analyses and simulations to the behavior of MIMO system and its expected capacity for various channel distribution under flat fading. Several types of distributions (Ric...

A key element for many fading-compensation techniques is a (long-range) prediction tool for the fading channel. A linear approach, usually used to model the time evolution of the fading process, does not perform well for long-range prediction applications. In this article, we propose an adaptive fading channel prediction algorithm using a sum-sinusoidal-based state-space approach. This algorith...
