Package: comm

Demodulate using CPM method and Viterbi algorithm


Y = step(H,X)


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:   H 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.
