The core objective of this project is to design and implement a QPSK/BPSK demodulation system using a DNN at the receiver end ...
Abstract: The six-polarization shift keying quadrature (6PolSK-QPSK) has been proved to be an alternative to four-dimensional (4D ...
Four-dimensional QPSK modulation transmission scheme based on entropy-coding-aided symbol selection.
We propose a four-dimensional quadrature phase shift keying (4D-SS-QPSK) modulation transmission scheme based on entropy-coding ...
本科学的通信读研了没在做，也算是出于兴趣完成的工程，难免有纰漏 ...
As an important part of the communication system, synchronization technology is a communication system to run the correct ...
For the QPSK modulator shown in the figure above, construct the truth table, phasor diagram, and constellation diagram.
A DP-QPSK system incorporates four modulator drivers, each delivering output voltages as high as 7.0 V p-p. An example is Inphi’s IN3212SZ Mach-Zehnder modulator driver (Fig. 3). Due to the large ...
Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods.
