Deinterleave input sequence


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) restores the original ordering of the sequence, X, that was interleaved using a block interleaver. The step method forms the output, Y, based on the mapping specified by the PermutationVector property as Output(PermutationVector(k))=Input(k), for k = 1:N, where N is the length of the permutation vector. The input X must be a column vector of the same length, N. The data type of X can be numeric, logical, or fixed-point (fi objects). Y has the same data type as X.


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.
