We present a method for learning a function over distributions. The method is based on generalizing nonparametric kernel regression by using the earth mover’s distance as a metric for distribution space. The technique is applied to the problem of l

Singular Spectral Analysis (SSA) is a powerful technique for separating arbitrary co-channel signals in a single channel receiver. The technique is based on a subspace projection using eigenvector decomposition (EVD). While choosing the number of eig

This paper addresses the asymptotic behavior of a particular type of information-plus-noise-type matrices, where the column and row numbers of the matrices are large and of the same order, while signals have diverged and the time delays of the channe

Recently, a simple approximate framework has been developed to evaluate signal-to-interference ratio (SIR) distribution in downlink cellular networks. This framework approximates the SIR distribution in a network model based on a non-Poisson point pr

Unmanned-aerial-vehicles (UAVs) are intended to be a vital part of beyond 5G (B5G) and 6G communication networks. UAV-to-ground communications in urban and populated areas are usually exposed to highly variable propagation conditions that can be ofte

Using stochastic gradient search and the optimal filter derivative, it is possible to perform recursive maximum likelihood estimation in a non-linear state-space model. As the optimal filter and its derivative are analytically intractable for such a

Generally, the value of a shape parameter will affect the accuracy of the radial point interpolation method (RPIM). However, a small shape parameter will cause this meshless method become unstable. In this paper, we expand the Gaussian basis function

In this paper, we propose a nonconvex penalty function for sparse signal recovery by using infimal convolution approximation. First, we show that this penalty function is between the l 1 -norm and the difference of l 1 and l 2 -norm (l 1 2- norm), th

Although the compressed sensing model has a good effect on signal recovery, it is quite difficult to design reconstruction algorithms for compressive sensing. The challenge is that the sampling rate is low, the sparsity is high, which makes it diffic

In this paper, we investigate the performance of a wireless-powered energy beamforming system with a multiple-antenna access point (AP) and a single-antenna user (SU). The SU first harvests radio frequency (RF) energy from the AP in the downlink (DL)
