Performs deinterleaving by writing the input data into an m(rows) × n(columns) matrix, column by column, and then reading the data out row by row when the matrix is full. Typically, block interleaver and deinterleaver functions are used together.

Rearranges, or depermutes, the permuted data.

Performs deinterleaving using delays that are computed based on the delays defined for the corresponding interleaver.
