System object: comm.DQPSKDemodulator
Package: comm

Demodulate using DQPSK method


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 DQPSK demodulator System object, H, and returns Y. Input X must be a single or double precision data type scalar or column vector. 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.
