Examine 16-QAM Using MATLAB - MathWorks
The modulation scheme uses baseband 16-QAM, and the signal passes through an additive white Gaussian noise (AWGN) channel. The basic simulation operations use these Communications Toolbox™ and MATLAB® functions.
Rectangular QAM Modulator Baseband - MathWorks
The Rectangular QAM Modulator Baseband block modulates the input signal using M-ary quadrature amplitude modulation with a constellation on a rectangular lattice. The output is a baseband representation of the modulated signal.
Use Pulse Shaping on 16-QAM Signal - MathWorks
Apply 16-QAM modulation using the qammod function. Use the upfirdn function to upsample the signal by the oversampling factor and apply the RRC filter. The upfirdn function pads the upsampled signal with zeros at the end to flush the filter. Then, the function applies the filter.
