1. An address generation apparatus for a quadratic permutation polynomial (QPP) interleaver, comprising: a basic recursive unit; and L recursive units, represented as a first unit to L-th -1, said apparatus inputs a plurality of configurable parameters, serially generates a plurality of interleaver addresses by using said basic recursive unit, and parallel generates L sets of corresponding interleaver addresses by using said first to L-th recursive units, wherein whenever said basic recursive unit or said j-th recursive unit generates an interleaver address, the interleaver address generated by said basic recursive unit is outputted to said first recursive unit, while the interleaver address generated by said j- th recursive unit is outputted to said (j+l)-th recursive unit, Π(i) is the i-th interleaved address generated by said apparatus, f1 and f2 are QPP coefficients, k is information block length of an input sequence, 1ik-1, 1jL-1, and mod is modulus computation.
