System object: comm.Scrambler
Package: comm

Scramble input signal


Y = step(H,X)
Y = step(H,X,IC)
Y = step(H,X,RESET)


    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) scrambles input data, X, and returns the result in Y. X must be a double precision, logical, or integer column vector. The output Y is same data type and length as the input vector.

Y = step(H,X,IC) scrambles the input data given initial values of the linear feedback shift register, IC. The length of IC must be the same as order of the Polynomial property. This syntax is available when InitialConditionsSource is set to Input port.

Y = step(H,X,RESET) resets the state of the scrambler when a nonzero value is applied as an input to the RESET argument. This syntax is available when InitialConditionsSource is set to Property and ResetInputPort is true.

    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 (MATLAB) 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.
