Recover symbol timing phase using fourth-order nonlinearity method


[Y,PHASE] = step(H,X)
[Y,PHASE] = step(H,X,R)



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,PHASE] = step(H,X) performs timing phase recovery and returns the time-synchronized signal, Y, and the estimated timing phase, PHASE, for input signal X. X must be a double or single precision complex column vector.

[Y,PHASE] = step(H,X,R) restarts the timing phase recovery process when you input a reset signal, R, that is non-zero. R must be a logical or double scalar. This syntax applies when you set the ResetInputPort property to true.


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.
