System object: comm.MatrixHelicalScanDeinterleaver
Deinterleave input symbols by filling a matrix along diagonals
Y = step(H,X)
Y = step(H,X) restores the original ordering of the sequence, X. The object fills a permutation matrix with the input symbols in a helical fashion and output the contents row by row, and returns Y. The input X must be a NumRows NumColumns long column vector and the data type 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.
