Low-Complexity Lattice Reduction Aided Schnorr Euchner Sphere Decoder Detection Schemes with MMSE and SIC Pre-processing for MIMO Wireless Communication Systems
(IEEE Computer Society, 2022-03-03)
The LRAD-MMSE-SIC-SE-SD (Lattice Reduction Aided Detection - Minimum Mean Squared Error-Successive Interference Cancellation - Schnorr Euchner - Sphere Decoder) detection scheme that introduces a trade-off between performance ...
Brain-like Initial-boosted Hyperchaos and Application in Biomedical Image Encryption
(2022-03-03)
Neural networks have been widely and deeply studied in the field of computational neurodynamics. However, coupled neural networks and their brain-like chaotic dynamics have not been noticed yet. This paper focuses on the ...
Proof of Concept of a Low-Cost Beam-Steering Hybrid Reflectarray that Mixes Microstrip and Lens Elements Using Passive Demonstrators
(2022-02-11)
In this article, a proof-of-concept study on the use of a hybrid design technique to reduce the number of phase shifters of a beam-scanning reflectarray (RA) is presented. An extended hemispherical lens antenna with feeds ...
An Isolated ZVS DC/DC Converter with Diode-connected MOSFET in Rectifier
(Institute of Electrical and Electronics Engineers (IEEE), 2022-02-02)
This paper presents an isolated resonant zero voltage switching ZVS converter with a diode-connected MOSFET in a rectifier. The active resonant network is the composition of a resonant capacitor, a transformer leakage ...
A locally active discrete memristor model and its application in a hyperchaotic map
(2022-01-23)
The continuous memristor is a popular topic of research in recent years, however, there is rare discussion about the discrete memristor model, especially the locally active discrete memristor model. This paper proposes a ...
