System object: comm.RectangularQAMModulator
Package: comm
(To be removed) Modulate using rectangular QAM method
comm.RectangularQAMModulator will be
removed in a future release. Use qammod instead.
Y = step(H,X)
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, such as dimensions,
complexity, and data type of the input data. If you change a nontunable
property or an input specification, the System object issues an
error. To change nontunable properties or inputs, you must first call
the release method to unlock the object.
