Until the last few years, the narrow bandwidth (300kHz) of the 950MHz radio channels, which was adequate for the audio and technical standards of the all-analog world, was insufficient to handle the ...

The adoption of sophisticated phase-shift modulation schemes could make optical communication at 100 Gbit s −1 a reality within the next couple of years, but this is ultimately dependent on the ...

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 ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Fig 1. In this view of the architecture of an optical analyzer, the coherent reference receiver serves as the optical front end to the digitizer, taking as inputs two single-mode fibers, one carrying ...
