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.

Bit Error Rate Simulation Using 16 QAM Technique in Matlab In this paper, the authors introduce the Bit Error Rate (BER) simulation using 16 QAM (Quadrature Amplitude Modulation) in Matlab. Bit error ...

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 ...

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 ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

This chapter presents a design of the quadrature amplitude modulation (QAM) transmitter and receiver in Simulink and obtains the bit error rate (BER) graphs through ...
