Hadamard Product Perspective on Source Resolvability of Spatial-smoothing-based Subspace Methods

ICASSP 2019accepted

Spatial smoothing is a common preprocessing scheme for subspace methods that resolves their sensitivity to coherent sources. The source resolvability problem of spatial-smoothing-based subspace methods has been extensively investigated using different analysis techniques. In this paper, a unified Ha…

Prediction Performance After Learning in Gaussian Process Regression

AISTATS 2017poster

This paper considers the quantification of the prediction performance in Gaussian process regression. The standard approach is to base the prediction error bars on the theoretical predictive variance, which is a lower bound on the mean square-error (MSE). This approach, however, does not take into a…

Rate optimization for massive MIMO relay networks: A minorization-maximization approach

ICASSP 2016accepted

We consider the problem of sum-rate maximization in massive MIMO two-way relay networks with multiple (communication) operators employing the amplify-and-forward (AF) protocol. The aim is to design the relay amplification matrix (i.e., the relay beamformer) to maximize the achievable communication s…
