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 ...
In space exploration, long-distance optical links can now be used to transmit images, films and data from space probes to Earth using light. But in order for the signals to reach all the way and not ...
Six-port receiver architectures employ a passive network of couplers and detectors to transform radio-frequency signals directly into baseband information without the need for conventional mixers. By ...
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 ...
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 ...
