APPARATUS AND METHOD FOR ADDRESS GENERATION OF DATA INTERLEAVER/DEINTERLEAVER

摘要

An apparatus and a method for generating an address of a data interleaver/deinterleaver remove an address generation error of the deinterleaver by generating the address by an address generation polynomial of the interleaver. An address generation device of an interleaver includes an exponent decision unit, a coefficient calculation unit, and an address generation unit. The exponent decision unit(210) calculates a prime factor comprising the size of a bit and decides the exponent according to the number of the prime factor. The coefficient calculation unit(230) calculates the coefficient of the address generation polynomial of the interleaver base on the prime factor and the exponent. The address generation unit(250) generates the address by the polynomial using the coefficient.
