Abstract
A method of performing interleaving and a data transmission apparatus are disclosed, in which interleaving is performed for input data streams using bit reverse ordering (BRO) operation. A method of performing interleaving for input data streams comprises writing respective bits of the input data stream in a row direction of a memory matrix in accordance with the input order, performing row permutation for index of each row of the memory matrix using an R-bit (R is an integer) bit reverse ordering (BRO) operation, performing pruning for a row which satisfies a given condition, performing column permutation using BRO operation for index of each column of the memory matrix, and reading to output each bit in a column direction of the memory matrix where the column permutation has been performed.
