Abstract: This paper presents the design, implementation, and experimental validation of a distributed multiple-input multiple-output (dMIMO) testbed. The testbed comprises 24 spatially distributed ...

This list contains a large library of images and details on "RF Taps" community members have done to get signals out of there VCRs, VTRs, Camcorders & Open-Reel ...

Abstract: In the instrument system for noninvasive quantitative analysis of blood components by dynamic spectrum (DS), there are problems with low signal-to-noise ratio (SNR) and wide bandwidth ...

This process is called modulation and demodulation, respectively, and it’s where the “mo-dem” gets its name. Typically, your internet service provider (ISP) will offer you a modem for a small monthly ...

In the last decades, the demand for a low-cost, day-night, all-weather spaceborne imaging capability pushes to further development of synthetic aperture radar (SAR) systems, as satellite payload ...

This paper presents experimental realization of an ultralow power wireless communication method that works by selectively connecting or disconnecting an impedance-matched resistor and an antenna. This ...

With the development of informatization and intellectualization technology, the power system has become the cyber-physical power system (CPPS) with deep integration of the cyber side and the physical ...

A-BPSK aviation binary phase shift keying—a form of phase-shift keyed modulation with shaped filters especially adapted to perform in an RF environment subject to fading A-QPSK aeronautical quadrature ...

Complex, highly sophisticated communication is fundamental to the human experience — to being human. Play is likewise important to our intellectual, creative, and social development. Today much of our ...

Brain–computer interface (BCI) technology provides a new communication channel. However, current applications have been severely limited by low communication speed. This study reports a noninvasive ...
