System object: comm.BlockInterleaver
Package: comm

Permute input symbols using a permutation vector


Y = step(H,X)


Y = step(H,X) permutes input sequence, X, and returns interleaved sequence, Y. The step method forms the output Y, based on the mapping defined by the PermutationVector property as Output(k)=Input(PermutationVector(k)), for k = 1:N, where N is the length of the PermutationVector property. The input X must be a column vector of length N. The data type of X can be numeric, logical, or fixed-point (fi objects). Y has the same data type as X.

    Note:   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.
