aIn an environment where a direct line-of-sight signal coexists with a diffused signal component, Rician distribution has been proven to be a more accurate model for the fading statistics. 在环境,一个直接视行信号共存与一个散开的信号组分, Rician发行被证明是一个更加准确的模型为退色的统计。[trans...
An exact expression for the joint density of three correlated Rician variables is not available in the open literature. In this letter, we derive new infinite series representations for the trivariate Rician probability density function (pdf) and the joint cumulative distribution function (cdf). Our...
This paper investigates the distribution characteristics of Fourier, discrete cosine, and discrete sine transform coefficients in T1 MRI images. This paper reveals their adherence to Benford's law, characterized by a logarithmic distribution of first digits. The impact of Rician noise...

To further characterize the processes modulated by tSMS, we fitted drift-diffusion models to our behavioral data (Fig. 2e). These models assume that the decision process in each trial of the CRT task occurs as a noisy diffusion process that accumulates evidence until either a positive or a neg...
The magnitude operation changes the signal distribution in MRI images from Gaussian to Rician. This introduces a bias that must be taken into account when estimating the apparent diffusion coefficient. Several estimators are known in the literature. In the present paper, two novel schemes are ...
