1. An interleave-deinterleave apparatus comprising:
an interleave/deinterleave memory unit that performs both interleave and deinterleave operations during turbo decoding;
a pair of address selecting units, one selecting unit selectively connecting outputs of an address generating unit as a writing address of said interleave/deinterleave memory unit and another selecting unit connecting outputs of an address generating unit as a reading address for said interleave/deinterleave memory unit; and
an address selection control unit for controlling the pair of address selecting units to effect operation of the interleave/deinterleave memory unit as an interleaver and a deinterleaver in a time divisional manner.
