Hopfield Learning-based and Nonlinear Programming methods for Resource Allocation in OCDMA Networks
Cristiane A. Pendeza Martinez, Taufik Abrão, Fábio Renan Durand +1
This paper proposes the deployment of the Hopfield's artificial neural network (H-NN) approach to optimally assign power in optical code division multiple access (OCDMA) systems. F…
Massive MIMO for Internet of Things (IoT) Connectivity
Alexandru-Sabin Bana, Elisabeth de Carvalho, Beatriz Soret +4
Massive MIMO is considered to be one of the key technologies in the emerging 5G systems, but also a concept applicable to other wireless systems. Exploiting the large number of deg…
Pre-distortion and Pre-equalization for Non-Linearities and Low-Pass Effect Mitigation in OFDM-VLC Systems
Luis Carlos Mathias, Jose Carlos Marinello Filho, Taufik Abrao
The orthogonal frequency division multiplexing (OFDM) transmission has shown promise in applications of visible light communication (VLC). However, the variation of the nonlinearit…
Randomized Kaczmarz Algorithm for Massive MIMO Systems with Channel Estimation and Spatial Correlation
Victor Croisfelt Rodrigues, Jose Carlos Marinello Filho, Taufik Abrao
To exploit the benefits of massive multiple-input multiple-output (M-MIMO) technology in scenarios where base stations (BSs) need to be cheap and equipped with simple hardware, the…
Total Energy Efficiency of TD- and FD-MRC Receivers for Massive MIMO Uplink
Jose Carlos Marinello, Cristiano Panazio, Taufik Abrao +1
This paper proposes a detailed investigation on the uplink (UL) performance of massive multiple-input-multiple-output (maMIMO) systems employing maximum-ratio combining at the rece…
Exponential Spatial Correlation with Large-Scale Fading Variations in Massive MIMO Channel Estimation
Victor Croisfelt Rodrigues, Jose Carlos Marinello, Taufik Abrao
To provide the vast exploitation of the large number of antennas on massive multiple-input-multiple-output (M-MIMO), it is crucial to know as accurately as possible the channel sta…
