System object: comm.CPMDemodulator
Package: comm
Demodulate using CPM method and Viterbi algorithm
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) demodulates input data, X,
with the CPM demodulator System object, H,
and returns Y. X must be a double
or single precision, column vector with a length equal to an integer
multiple of the number of samples per symbol specified in the SamplesPerSymbol property.
Depending on the BitOutput property value, output Y can
be integer or bit valued.
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.
