System object: comm.RectangularQAMModulator
Namespace: comm

(Removed) Modulate using rectangular QAM method

comm.RectangularQAMModulator has been removed. Use qammod instead.

Syntax

Y = step(H,X)

Description

Note

Starting in R2016b, instead of using the step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.

Y = step(H,X) modulates input data, X, with the rectangular QAM modulator object, H. It returns the baseband modulated output, Y. Depending on the value of the BitInput property, input X can be an integer or bit valued column vector with numeric, logical, or fixed-point data types.

Note

obj specifies the System object on which to run this step method.

The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications. For more information on changing property values, see System Design in MATLAB Using System Objects.
