ABSTRACT:
According to one aspect of the invention, a method of interleaving data for enabling data coding in a communication network is disclosed, the method including storing parameters required to output address sequences for a matrix, receiving a block size associated with a block of data at a circuit for interleaving data, outputting parameters associated with the stored parameters based upon the block size, and producing an address sequence using the parameters. A circuit for interleaving data for data coding in a communication network is also disclosed. The circuit includes a lookup table storing parameters required to output address sequences for a matrix. A search coupled to the lookup table receives a clock size associated with a matrix and outputs parameters based upon the block size. A computation circuit coupled to receive the parameters outputs an address sequence using the parameters.
