Digital modulation is the technique in which the discrete changes in a message signal are imposed onto parameters (amplitude, frequency, or phase) of a sinusoidal carrier wave. This chapter summarizes ...

Phase-modulation and -demodulation techniques are more complex than modulation and demodulation based on amplitude and frequency. However, they provide the benefit of higher data rates for the amount ...

Modulation and demodulation techniques are described for an optical PSK heterodyne transmission system operating at 560 Mb/s and 1.2 Gb/s. Performance limitations affecting the receiver sensitivity in ...

Phase Shift Keying (PSK) modulation and demodulation circuit simulations (via LTspice and Proteus) also contains the pcb gerbers. This repository contains simulation files and circuit diagrams for ...

Implement and demonstrate different digital modulation techniques, including Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK). Visualize the modulation and ...

Learn the basics of QPSK demodulation, the challenges of noise and interference, and some tips to improve your demodulator's performance and reliability.

DiBcom and TeamCast have teamed up to provide programmable mobile TV solutions that can be configured similarly to meet the modulation and demodulation requirements of current broadcast standards, ...
