System object: comm.Descrambler
Descramble input signal
Y = step(H,X)
Y = step(H,X,IC)
Y = step(H,X,RESET)
Y = step(H,X) descrambles 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, X.
Y = step(H,X,IC) descrambles 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 descrambler 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: 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.
