Version:

Maps an incoming bit stream to complex-valued QAM symbols.

Use this node in conjunction with
MT Matched Filter,
MT Align to Ideal Symbols,
MT Decimate Oversampled Waveform, and
MT Calculate BER to perform waveform analysis on the modulated waveform.
**Note**

The mapping of symbols to bits depends on the number of bits per symbol, which equals
${\mathrm{log}}_{2}\left(M\right)$ with *M* representing the size of the modulation scheme. For example, in a 256-QAM system, 500 QAM symbols are mapped to
$\left(500\right)\times {\mathrm{log}}_{2}\left(256\right)=4000\text{\hspace{0.17em}}\text{\hspace{0.17em}}message\text{\hspace{0.17em}}\text{\hspace{0.17em}}\text{\hspace{0.17em}}bits$.
