Reduced feedback schemes using random beamforming in MIMO broadcast channels
A random beamforming scheme for the Gaussian MIMO broadcast channel with channel quality feedback is investigated and extended. Considering the case where the receivers each have r...

A parallel architecture for implementation of filters based on order statistics
A new approach for implementing filters based on order statistics is proposed in this letter. As an illustration realisations of range, a-trimmed mean and WMMR filters are present...

Beyond second-order statistics for learning: A pairwise interaction model for entropy estimation
Second order statistics have formed the basis of learning and adaptation due to its appeal and analytical simplicity. On the other hand, in many realistic engineering problems requ...

Comparison among Three Estimators for High Order Statistics
Most of recent and important algorithms in signal processing (for blind identification or separation, etc) are based on higher order statistics (HOS). And most of them use a crite...

Sigma Set: A small second order statistical region descriptor
Given an image region of pixels, second order statistics can be used to construct a descriptor for object representation. One example is the covariance matrix descriptor, which sh...
