Our PSK example in equations (5.75a) and (5.75b) above is shown as example in Figure 5-9(a). Since M = 2, i.e. that we have a binary system, this modulation type is called binary phase shift keying ...

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 ...

Amplitude phase shift keying (APSK), a variation of both M-PSK and QAM, was created in response to the need for an improved QAM. Higher levels of QAM such as 16QAM and above have many different ...

This phase-shift keying (PSK) results in a bit rate of 31 – slower than RTTY, but designed to keep up with the average typist.

Digital information often must travel through analog channels in applications like satellite communication, digital cellular phones, digital microwave communication, and others. This transmission ...

They were measured with the 30 m high-gain antenna of the German Space Operations Center (GSOC) in Weilheim, Germany, on Jan. 17, 2024. The largest and sharpest peak in the L1 band at 1,598.625 MHz ...
