In this paper, we propose a practical structured constellation for non-coherent
communication with a single transmit antenna over Rayleigh flat and block fading channel …

In frequency-division duplex full-dimension massive MIMO systems, one of the main
challenges is to obtain sufficiently accurate channel state information (CSI) at the transmitter …

In frequency division duplex (FDD) multiple-input multiple-output (MIMO) wireless
communications, limited channel state information (CSI) feedback is a central tool to support …

We consider classification of points on a complex-valued Grassmann manifold of-
dimensional subspaces within the-dimensional complex Euclidean space. We introduce a …

This paper focuses on random uplink transmissions of a subset of nodes disseminated in a
cell. Under the constraints of massive Machine Type Communication (mMTC) in cellular Low …

In this paper, we introduce and analyze a practical codebook for single-antenna non-
coherent communications, with codewords belonging to the Grassmannian of lines defined …

We propose novel compression algorithms for time-varying channel state information (CSI)
in wireless communications. The proposed scheme combines (lossy) vector quantisation …

We propose a novel recursive multi-stage approach to Grassmannian quantization.
Compared to the commonly employed single-stage quantization, our method has the …

spread spectrum multiple access scheme for underwater acoustic mobile multiple access …

We propose novel tree-structured quantization approaches for points on Grassmann and
Stiefel manifolds. Such manifold quantizers find application, eg, for channel state information …
