Contains codes various Digital Modulation Schemes (like AM, DSB-SC, SSB-SC FM, BPSK, QPSK, 16-QAM, DBPSK, DQPSK) in MatLab from scratch ie. without built-in MatLab functions ...

Demonstrates concepts of Amplitude Modulation (AM) using Matlab/GNU Octave to modulate using DSB-SC a sinc(x), demodulate synchronously and perform a Low Pass filtering at frequency domain.

Abstract: This paper presents an approach for studying the amplitude modulation and demodulation. An algorithm for the laboratory exercise and block diagrams for MATLAB Simulink used in it, are ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...
