Optimization of a Multi-criteria Cognitive Radio User Through Autonomous Learningce between different users of the same radio spectrum. Cognitive radio provides an ideal and balanced solution to these types of problems (overload and congestion in the spectrum). The cognitive radio concept is based on the flexible use of any available frequency band of the radio spectrum that cou

Channel Estimation in Massive MIMO Systems for Spatially Correlated Channels with Pilot Contaminatioding channels are correlated in the spatial domain. An appropriate exponential correlation (EC) is using as an approximation model for uniform-linear arrays (Un-LA). The statistics of minimum mean square error (MMSE), element-wise MMSE (EW-MMSE), approximate MMSE (Approx.MMSE), and least-squares (LS

On Channel Estimation of Uplink TDD Massive MIMO Systems Through Different Pilot Structuresems is studied by operating at Uplink (UL) phase according to a time division duplex (TDD) scheme using commonly known channel estimators existing in the literature. The least squares (LS) and minimum mean square error (MMSE) channel estimators are investigated with three categories of pilots, namel

NarrowBand-IoT and eMTC Towards Massive MTC: Performance Evaluation and Comparison for 5G mMTCed new requirements other than throughput to support a massive deployment of devices for massive machine-type communication (mMTC). Therefore, more importance is accorded to coverage, latency, power consumption and connection density. To this purpose, the third generation partnership project (3GPP)

Real-Time Distributed Pipeline Architecture for Pedestrians’ Trajectories, 1.35 million people perish each year as a consequence of road accidents and more end up with serious injuries. One of the most recurrent factors is distracted driving. 16% of pedestrian injuries were triggered by distraction due to phone use, and the amount of pedestrian accidents caused by mobile
