This section discusses the hardware architectures of MAs and RAs from the perspective of antenna-level implementation and array-level integration. They can be realized through mechanical, fluidic, ...

Abstract: With the deployment of high speed train (HST) systems increasing worldwide and their popularity with travelers growing, providing broadband wireless communications (BWC) in HSTs is becoming ...

This work presents an adaptive hybrid signal precoding strategy for Cell-Free (CF) Massive multiple-input multiple-output (MIMO) systems. The proposed solution exploits the advantages of both ...

The SparkFun GNSS Flex breakout is a carrier board for our GNSS Flex modules. In its simplest form, the GNSS Flex Breakout board provides access to all of the interfaces from a GNSS Flex module. Need ...

Each SparkPNT GNSS Flex module features a different GNSS receiver. These boards breakout the various interfaces of a GNSS receiver to the standardized pin configuration for the female headers of the ...

Neural responses evoked by a stimulus reduce upon repetition. While this adaptation allows the sensory system to attend to novel cues, does information about the recurring stimulus, particularly its ...

Abstract: This study investigates and experimentally demonstrates a novel polarization scrambling method to solve the polarization dependence of remote electro-optic modulation in the fiber-based ...

Digital beamforming phased arrays are becoming an increasingly common antenna product both for defense and commercial applications. The primary technological advancement making this possible is the ...

As wireless networks move to millimetre-wave (mm-wave) and terahertz (THz) frequencies for 5G communications and beyond, ensuring security and resilience to eavesdropper attacks has become ...

This article presents a holographic metasurface antenna with stochastically distributed surface impedance, which produces randomly frequency-diverse radiation patterns. Low mutual coherence electric ...

The growing demand of extremely high-data-rate services, together with emerging advanced Internet of Things (IoT) and Industry 4.0 applications bring new technical challenges to wireless ...
