INTERLEAVING APPARATUS

摘要

Interleave of plural types are realized, and decoding adaptively corresponding to codes of various types is conducted through a simple constitution. An interleaver (100) of an element decoder has a plurality of storage circuits (407) where data is stored, a control circuit (400) for generating address data for writing data in the storage circuits (407) and address data for reading the data from the storage circuits (407), an address selecting circuit (405) for selecting address data to be distributed to the storage circuits (407) in accordance with the mode indicating the structure of codes including the type of interleave to be conducted, an input data selecting circuit (406) for selecting data to be distributed to the storage circuits (407) in accordance with the mode, and an output data selecting circuit (408) for selecting data to be outputted in accordance with the mode. A storage circuit to be used is selected from among the storage circuits (407).
