  • Method and apparatus for interleaving in a communication system
    Patent number: 6463556
    Abstract: Interleaving within a communication system occurs by finding a minimum value (m) such that that N<=2n×(2m−1), wherein N is an interleave block length, and n is a predetermined fixed value. A maximum-length sequence generator is initialized to 1 and a bit reverse sequence generator is initialized to 0. An n bit output is determined from the bit reverse sequence generator, and an m bit output is determined from the maximum length sequence generator. Finally, the n bit output is used as a most significant bit and the m bit output is used as a least significant bit for an interleaver address.
