Four-phase phase shift keying (QPSK) circuit structure is relatively simple, and has a good band utilization, in the modern communication has a wide range of applications. Corresponding research on ...

Therefore, we design a FSO communication system based on 16-ary phase shift keying orthogonal frequency division multiplexing (16PSK-OFDM).The simulation experiment is carried out, and the influence ...

All the latest science news on phase shift from Phys.org. Find the latest news, advancements, and breakthroughs.

In this letter, we experimentally demonstrate Brillouin echoes-based distributed optical fiber sensing with centimeter spatial resolution. It is based on a differential phase-shift-keying technique ...

This letter considers the average symbol error rate (SER) of M-ary phase shift keying (M-PSK) over the α-η-μ fading channels subject to additive Laplacian noise.

The phase diagram has a closed-loop binodal (as in associative phase diagrams) with two critical points. One critical point is in common with the strong driving force cases, that is, the system loses ...
