This project implements a fully digital system on an FPGA to convert an 8-bit parallel data input into a QPSK (Quadrature Phase-Shift Keying) modulated baseband signal. The system is designed as a ...
Eliminating software adjustments in circuits based on digital logic improves robustness and reduces cost for small-production-run series. This circuit is a cost-improved version of classical QPSK ...
This paper is the study of the QPSK (Quadrature Phase Shift keying) modulation technique using AWGN (Additive White Gaussian Noise) and Multipath Rayleigh fading channel. In QPSK scheme the authors ...
In recent years, the expansion of new services such as cloud computing and on-line streaming has brought about a dramatic increase in data communications. As the data transmission volume of ...
Quadrature phase shift key is a one of the digital modulation schemes that use Phase-shift keying. One popular varient of QPSK is offset QPSK or OQPSK. What is the difference between these two ...
Abstract: A 50-Mb/s quadrature phase-shift keying (QPSK)/offset quadrature phase-shift keying (O-QPSK) transmitter suitable for biomedical high-quality imaging application is presented. Centered at ...
Free Space Optics is the technology which implies the line-of-sight link for the transfer of data between two distant points. The beam of light is used to provide optical connection that can transmit ...
The rapid increase in the volume of communications traffic that has resulted from the spread of new services such as cloud computing and on-line streaming in recent years has created demand to put the ...
Abstract: In the field of modern mobile communication, (Quadrature Phase Shift Keying) QPSK modulation technology is widely used, which has a great advantage that it can work normally in a limited ...
