Sparse NOMA: A Closed-Form Characterization
Benjamin M. Zaidel, Ori Shental, Shlomo Shamai
Understanding fundamental limits of the various technologies suggested for future 5G and beyond cellular systems is crucial for developing efficient state-of-the-art designs. A lea…
Low-Density Code-Domain NOMA: Better Be Regular
Ori Shental, Benjamin M. Zaidel, Shlomo Shamai
A closed-form analytical expression is derived for the limiting empirical squared singular value density of a spreading (signature) matrix corresponding to sparse low-density code-…
Applications of Large Random Matrices in Communications Engineering
Ralf R. Müller, Giusi Alfano, Benjamin M. Zaidel +1
This work gives an overview of analytic tools for the design, analysis, and modelling of communication systems which can be described by linear vector channels such as y = Hx+z whe…
The Finite State MAC with Cooperative Encoders and Delayed CSI
Ziv Goldfeld, Haim H. Permuter, Benjamin M. Zaidel
In this paper, we consider the finite-state multiple access channel (MAC) with partially cooperative encoders and delayed channel state information (CSI). Here partial cooperation…
Vector Precoding for Gaussian MIMO Broadcast Channels: Impact of Replica Symmetry Breaking
Benjamin Zaidel, Ralf Mueller, Aris Moustakas +1
The so-called "replica method" of statistical physics is employed for the large system analysis of vector precoding for the Gaussian multiple-input multiple-output (MIMO) broadcast…
On the Spectrum of Large Random Hermitian Finite-Band Matrices
Oren Somekh, Osvalso Simeone, Benjamin M. Zaidel +2
The open problem of calculating the limiting spectrum (or its Shannon transform) of increasingly large random Hermitian finite-band matrices is described. In general, these matrice…
Cooperative Multi-Cell Networks: Impact of Limited-Capacity Backhaul and Inter-Users Links
Shlomo Shamai, Oren Somekh, Osvaldo Simeone +3
Cooperative technology is expected to have a great impact on the performance of cellular or, more generally, infrastructure networks. Both multicell processing (cooperation among b…
