This project involves the simulation, design, and analysis of Amplitude Modulation (AM) and Demodulation. The main objectives are: AM Modulation: Generating an AM signal using a switching modulator ...

In this paper, a new data modulation and demodulation scheme are proposed for the terahertz (THz) communications. The new data modulation scheme is named as M-ary pi/2 amplitude phase shift keying ...

Visible Light Communications (VLC) is a wireless communication system for enhanced 5G and 6G high speed wireless networks. VLC is one of the most accepted varieties of short-range wireless ...

Pulse position modulation into the category of analog communication. Pulse-Position modulation has the advantage of requiring constant transmitter power output, but the disadvantage of depending on ...

1. Three basic digital modulation formats are still very popular with low-data-rate short-range wireless applications: amplitude shift keying (a), on-off keying (b), and frequency shift keying (c).

To use SDR for modulation and demodulation, you need a hardware platform, such as a computer or a smartphone, that can connect to a radio frequency (RF) front-end, such as an antenna or a transceiver.
