Exploiting Spatial Channel Covariance for Hybrid Precoding in Massive MIMO Systems

Exploiting Spatial Channel Covariance for Hybrid Precoding in Massive MIMO Systems  Abstract: We propose a new hybrid precoding technique for massive multi-input multi-output (MIMO) systems using spatial channel covariance matrices in the analog precoder design. Applying a regularized zero-forcing precoder for the baseband precoding matrix, we find an unconstrained analog precoder that maximizes signal-to-leakage-plus-noise ratio […]


Probabilistic Models For Ad Viewability Prediction On The Web

Data-driven Soft Decoding of Compressed Images in Dual Transform-Pixel Domain Abstract In the large body of research literature on image restoration, very few papers were concerned with compression-induced degradations, although in practice, the most common cause of image degradation is compression. This paper presents a novel approach to restoring JPEG-compressed images. The main innovation is in the approach of exploiting […]
