Performance analysis of downlink MIMO-NOMA systems over Weibull fading channels
Lenin Patricio Jiménez Jiménez, Fernando Darío Almeida García, Maria Cecilia Luna Alvarado +4
This work analyzes the performance of a downlink multi-user multiple-input multiple-output (MU-MIMO) non-orthogonal multiple access (NOMA) communications system. To reduce hardware…
On Integer-Forcing Precoding for the Gaussian MIMO Broadcast Channel
Danilo Silva, Gabriel Pivaro, Gustavo Fraidenraich +1
Integer-forcing (IF) precoding, also known as downlink IF, is a promising new approach for communication over multiple-input multiple-output (MIMO) broadcast channels. Inspired by…
On the Exact Distribution of Mutual Information of Two-user MIMO MAC Based on Quotient Distribution of Wishart Matrices
Gabriel Pivaro, Santosh Kumar, Gustavo Fraidenraich
We propose the exact calculation of the probability density function (PDF) and cumulative distribution function (CDF) of mutual information (MI) for a two-user MIMO MAC network ove…
Outage Probability for Multi-Hop Full-Duplex Decode and Forward MIMO Relay
G. F. Pivaro, G. Fraindenraich
In this paper, a multi-hop (MH) decode-and-forward (DF) multiple-input multiple-output (MIMO) relay network has been studied. To consider a more realistic scenario, Full-Duplex (FD…
On the Exact and Approximate Eigenvalue Distribution for Sum of Wishart Matrices
S. Kumar, G. F. Pivaro, G. Fraidenraich +1
The sum of Wishart matrices has an important role in multiuser communication employing multiantenna elements, such as multiple-input multiple-output (MIMO) multiple access channel…
