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.
How many different symbols are possible at the output of a 16-QAM modulator?
So, in each symbol period, only one of the 'dots' is transmitted. As there are 16 symbols, this version of QAM is called 16-QAM. Figure 1.8 Constellation diagram for 16-QAM.
How to generate QAM?
Quadrature Amplitude Modulation with Bit Inputs
Modulate a sequence of bits using 64-QAM. Pass the signal through a noisy channel. Display the resultant constellation diagram. Set the modulation order, and determine the number of bits per symbol.
