Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

This project focuses on the design, simulation, and performance optimization of two key digital modulation techniques — Quadrature Phase Shift Keying (QPSK) and Offset Quadrature Phase Shift Keying ...

Abstract: As a matter of fact, digital modulation technology has developed in many directions in recent years, such as PSK, ASK, FSK and QAM. These modulation techniques have been widely adopted in ...
