Generates a symbol map with an input matrix of symbol values and I/Q symbol amplitude arrays that you specify. Use the symbol map parameter of the system parameters cluster to configure the operation of the demodulation and modulation nodes.
The symbol values matrix defines how the M-ary binary data are mapped to the discrete I/Q symbols on the constellation diagram. The optional gain parameter can be used to multiply the generated symbol map by a scalar value. The node internally reads the symbol values matrix row-wise and uses the I/Q symbol amplitudes array values to assign the symbol amplitudes to each element in the row.
The number of rows in the symbol amplitudes matrix must exactly equal the length of the symbol amplitudes (Q) array. Additionally, the number of columns of the symbol amplitudes matrix must exactly equal the length of the symbol amplitudes (I) array. If these conditions are violated, the node returns an error.
