System object: comm.CPMDemodulator
Package: comm

Demodulate using CPM method and Viterbi algorithm


Y = step(H,X)



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.


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.
