Communications System Toolbox

Analog and Digital Modulation

Analog and digital modulation techniques encode the information stream into a signal that is suitable for transmission. Communications System Toolbox provides a number of modulation and corresponding demodulation capabilities. These capabilities are available as MATLAB functions and objects, MATLAB System objects, and Simulink blocks.

Modulation types provided by the toolbox are:

Analog, including AM, FM, PM, SSB, and DSBSC

Digital, including FSK, PSK, BPSK, DPSK, OQPSK, MSK, PAM, QAM, and TCM
