The ever-increasing demand for more bandwidth to the home, office, and mobile devices is driving the deployment of 40G optical communications systems. Beginning in 2006, major carriers began deploying ...

The most basic forms of digital modulation are amplitude shift keying (ASK), frequency shift keying (FSK), and phase shift keying (PSK). ASK represents bit variations as different carrier ...

Binary FSK(Frequency Shift Keying) and PSK(Phase Shift keying) are extensively used in telecommunication for digital data transmission. FSK/PSK modulator circuits usually employ analogue components ...

In the early 1980s, I was working at a new division that built special-purpose modems. Our boxes were effective and efficient, working with well-known modulation, such as FSK (frequency-shift keying), ...

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 ...
