Recover symbol timing phase using fourth-order nonlinearity method

Syntax

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

Description

[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.

    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.
