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 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 ...

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 ...

Abstract: In the rapidly evolving landscape of modern communication systems, the demand for high-speed, reliable, and efficient data transmission has never been greater. This paper compares ...
