Low SNR – When Only Decoding
We investigate the issue of distributed receiver cooperation in a multiple-relay network with memoryless independent fading channels, where the channel state information can’t be obtained. The received signals at distributed receiving nodes are first compressed or quantized before being sent to the decoder via rate-limited cooperation channels for joint processing. We focus on the low SNR regim...
متن کاملCluster significance testing using the bootstrap.
Many of the statistical methods currently employed to analyze fMRI data depend on a response template. However, the true form of the hemodynamic response, and thereby the response template, is often unknown. Consequently, cluster analysis provides a complementary, template-free method for exploratory analysis of multidimensional fMRI data sets. Clustering algorithms currently being applied to f...
متن کاملAdaptive De-Noising of Low SNR Signals
In 1992 David Donoho has introduced the term de-noising. Despite its advantages, this method isn't used yet in communications. The goal of this paper is to adapt this method to the requirements of communications, especially for low SNR signals. Our contribution is a new threshold's value search method, that realizes the maximization of the signal to noise ratio at the output of the de-noising s...

The goal of this paper is to propose a new denoising method, using another strategy for the threshold selection and another wavelets transform. This new discrete wav...
