Fiber optics has been the center of all modern telecommunications with its capacity for high-speed, long-distance internet that many enjoy today. However, the continuing demand for internet traffic ...

In the new communication system from researchers at Chalmers University of Technology, in Sweden, a weak optical signal (red) from the spacecraft's transmitter can be amplified noise-free when it ...

Communications in space demand the most sensitive receivers possible for maximum reach, while also requiring high bit-rate operations. A novel concept for laser-beam based communications, using an ...

An ultra-wide-band receiver based on a harmonic selection technique to improve the operational bandwidth of 5G networks has been developed. Fifth generation (5G) mobile networks are now being used ...

Traditional small satellites are limited to single-polarization. This new technology allows them to use dual-polarization, effectively doubling their communication capacity and improving performance ...

Communications receiver architecture has evolved slowly over the years. The most common and successful configuration is the superheterodyne architecture, which translates the incoming signal to a ...

In this paper, we describe the effects of timing and gain mismatches on the sampled signal in the general case of M-channel time-interleaved analog-to-digital converters (TI-ADCs) and propose a ...

Tool suite helps avoid systems conflict in a crowded environment. Communication decision aids are enabling U.S. Navy shipboard-system developers to improve system designs and on-station communicators ...
