Description
Block General QAM Modulator Baseband modulates the signal using the quadrature amplitude modulation method. The output is a basic representation of the modulated signal.
Parameter Signal Constellation specifies a constellation by listing its points in a vector of complex numbers of length . The input values must be integers in the range . The block matches the input integer with the value in the signal constellation vector.

Details
The input signal is in the form of a scalar or vector with the values of the elements in the range of values , where — modulation order. If a binary vector is given, then the number of elements must be an integer multiple of the number of bits per character. The number of bits per character is .
