Pulse Modulation: • Transmits analog information by sampling continuous waveforms at regular intervals. • Information transmitted only at sampling times with synchronizing signals. • Original ...

This repository contains a MATLAB simulation of Fast Orthogonal Frequency Division Multiplexing with Index Modulation (Fast-OFDM-IM), a next-generation waveform combining Fast-OFDM and subcarrier ...

Abstract: This paper contains the study of modulation identification for both analog and digital signals using convolution neural network. Modulation classification involves identifying the modulation ...

Abstract: This paper compares the basic modulation for digital transmission: MPSK, (Multiple Phase Shift Keying), MQAM, (Multiple Quadrature Amplitude Modulation ...

The process of varying the AMPLITUDE of a sound, often periodically. An example of AM is the violinist's TREMOLO, where the amplitude of the vibrating string is rapidly altered by a movement of the ...
