This repository contains simulations of various digital modulation techniques using Python and NumPy/SciPy. The purpose is to visualize and understand baseband signal characteristics such as waveform ...

Half the bits are represented on the real axis and half the bits are represented on the imaginary axis. The in-phase and quadrature signals are independent level Pulse Amplitude Modulation (PAM) ...

Quadrature Amplitude Modulation (QAM) has been a fundamental component in the evolution of mobile connectivity. As the demand for faster data speeds and more efficient network utilization continues to ...

Abstract: As a matter of fact, digital modulation techniques such as Phase Shift Keying (PSK) and Quadrature Amplitude Modulation (QAM) are very important for modern communication systems and are ...
