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 ...

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 ...

As quantum computers continue to advance, many of today's encryption systems face the risk of becoming obsolete. A powerful ...

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 ...

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 ...

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 ...

A technical paper titled “Optimizing the Photodetector/Analog Front-End Interface in Optical Communication Receivers” was published by researchers at University of Toronto. “This article addresses the ...

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 ...

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 ...
