System object: comm.BlockDeinterleaver
Deinterleave input symbols using permutation vector
Y = step(H,X)
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.
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.
