Discrete Aware Tensor Completion via Convexized -Norm Approximation
Niclas Führling, Getuar Rexhepi, Giuseppe Abreu
We consider a novel algorithm, for the completion of partially observed low-rank tensors, where each entry of the tensor can be chosen from a discrete finite alphabet set, such as…
Discrete-Aware Matrix Completion via Proximal Gradient
Hiroki Iimori, Giuseppe Thadeu Freitas de Abreu, Omid Taghizadeh +1
We present a novel algorithm for the completion of low-rank matrices whose entries are limited to a finite discrete alphabet. The proposed method is based on the recently-emerged p…
Fractional Programming for Robust TX BF Design in Multi-User/Single-Carrier PD-NOMA
Hiroki Iimori, Giuseppe Abreu, Koji Ishibashi
We present a new Beamforming-based (BB) Multiple-Input Single-Output (MISO)-Non-orthogonal Multiple Access (NOMA) scheme for Power Domain NOMA (PD-NOMA), in which the total transmi…
A Frame-Theoretic Scheme for Robust Millimeter Wave Channel Estimation
Razvan-Andrei Stoica, Giuseppe Thadeu Freitas de Abreu, Hiroki Iimori
We propose a new scheme for the robust estimation of the millimeter wave (mmWave) channel. Our approach is based on a sparse formulation of the channel estimation problem coupled w…
