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 ...

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 insatiable demand for bandwidth in our multimedia society is forcing system designers to focus efforts on the inevitable: systems operating at 40 Gbps And whether working on optical or electrical ...

Space communications: an illustration of the new concept for using light to communicate in space. (Courtesy: Yen Strandqvist/Chalmers University of Technology) The most sensitive receiver to date for ...

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 ...

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 ...

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 ...

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 ...

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 ...
