step

System object: comm.CPFSKDemodulator
Package: comm

Demodulate using CPFSK method and Viterbi algorithm

Syntax

Y = step(H,X)

Description

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 CPFSK demodulator System object, H, and returns Y. Input 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. For more information on changing property values, see System Design in MATLAB Using System Objects.
