Apparatus and method for processing interleaving/deinterleaving with address generator and channel encoding system using the same

摘要

An interleaving/deinterleaving processing method, a channel encoding system using it and a computer readable recording media for realizing it is provided. The interleaver includes: an interleaving storing unit for storing data sequence; the writing address generating unit for obtaining inter-location offset of a memory on which symbols are to be written in order to perform a writing operation and for generating a writing address to be practically written on, data and a memory control signal; an address offset generating unit for receiving a middle value (MID_OFF) and a start signal from the writing address generating unit, the middle value and the start signal being used for obtaining an offset between an inter-location offset of the memory; a reading address generating unit for generating increasing the address offset generating unit originated signal to as much as a symbol's memory inter-location offset; the first and the second selecting unit for selecting appropriate signal between a control signal and address in the writing address generating unit and the reading address generating unit transferred writing operation needed reading operation, and in a real interleaving operation needed reading operation; and a third selecting unit for selecting appropriate symbol in the memory output signals and performed from the reading address generating unit transferred interleaving.
