How to simulate QAM in Matlab?

y = pammod( x , M ) returns the complex envelope of the modulation of the input message signal, x , using PAM and the alphabet size, M . y = pammod( x , M , initphase ) specifies the initial phase of the modulated signal.

How do you make a constellation diagram in Matlab?

Create 32-QAM Constellation Diagram

Use the qammod function to generate the 32-QAM symbols with binary symbol ordering. M = 32; data = 0:M-1; sym = qammod(data,M,'bin'); Plot the constellation. Label the order of the constellation symbols.

How many bits in 16-QAM?

Each symbol in the constellation contains up to 4 bits (0s and 1s) in a 16-QAM scheme. Therefore, the number of combinations that are possible using 4 binary bits is 24 = 16, with each state or symbol containing a value from 0000 to 1111.
