Abstract
A method, an apparatus, and a computer program product for matching a rate of data bits to a desired rate by deletion of redundant data bits or repetition of data bits are disclosed. In a non-interleaved matrix of the data bits, a pattern of bits to be deleted or repeated to provide the desired data rate is determined. An address of each bit in the pattern in a manner inverse to the interleaving process is decoded to produce a respective address of the bit in the matrix. The respective bit in the interleaved data bits is deleted or repeated depending upon the respective address. The address decoding is performed in the same manner as a coding of addresses for producing the interleaved data bits from the non-interleaved matrix of the data bits.
