Hybrid Analog-Digital Precoding Revisited under Realistic RF Modeling
In this paper we revisit hybrid analog-digital precoding systems with emphasis on their modelling and radio-frequency (RF) losses, to realistically evaluate their benefits in 5G system implementations. For this, we decompose the analog beamforming networks (ABFN) as a bank of commonly used RF components and formulate realistic model constraints based on their S-parameters. Specifically, we conc...
متن کاملModeling of RF Waves in Free Space Optical Communication System Under Gamma-Gamma Turbulent Channel Effect
In this paper, an enhancement design of communication system using optical radio frequency (RF) waves in free space optical communication (FSO) system is presented. To our knowledge, it is the first time that the effect of Gamma-Gamma turbulent channel model on the performance of the proposed system is analyzed and simulated. To obtain an optical communication system with good performance and h...
متن کاملRf Vector Measurement Test-bench for Evaluation of Behavioral Model Accuracy under Realistic Excitation
This paper presents a simple test bench providing RF vector measurements of typical wireless communication system building blocks under realistic signal conditions. The instruments are synchronized by use of an experimental method based on an estimate of the signal path’s time delay. As an example, a complex digitally modulated signal with a carrier frequency of 2.45 GHz was used. The ultimate ...
متن کاملSensor Placement Revisited in a Realistic Environment
Ad-hoc networks of devices and sensors with (limited) sensing and wireless communication capabilities are becoming increasingly available for commercial and military applications. Under a national SensorNet initiative, we have built prototype deployment of a detection, identification, and tracking sensor-cyber network in a variety of locations including Washington D.C. and Port of Memphis. One ...
متن کاملRealistic single-neuron modeling
ALL NEUROPHYSIOLOGISTS are modelers . They may explain the bursting behavior of a neuron in terms of voltage-sensitive calcium currents and a calcium-activated potassium conductance . They may conclude from a complex spike waveform that the cell has excitable dendrites . They may choose to voltage-clamp the cell body to study synaptic currents. Behind each of their experimental designs and inte...
