System object: comm.GeneralQAMTCMModulator
Convolutionally encode binary data and map using arbitrary QAM constellation
Y = step(H,X)
Y = step(H,X,R)
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) convolutionally encodes and
modulates the input data,
X, and returns the encoded
and modulated data,
be of data type numeric, logical, or unsigned fixed point of word
length 1 (fi object). When the convolutional encoder represents a
rate K/N code, the length of
the input vector,
X, must be KL,
for some positive integer L. The
outputs a complex column vector,
Y, of length L.
Y = step(H,X,R) resets the encoder of the
general QAM TCM modulator object to the all-zeros state when you input
a non-zero reset signal,
be a double precision or logical scalar integer. This syntax applies
when you set the
ResetInputPort property to true.
obj specifies the System object on which to run this
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.
