APPARATUS AND METHOD FOR VITERBI DECODING

摘要

An apparatus and a method for viterbi decoding are provided to increase an operation speed by using a block processing decoding method. A viterbi decoder includes a distributor(281), a plurality of memory banks(283a-283h), a plurality of switches(285a-285h) and a plurality of decoding units(287a,287b). The distributor distributes the plurality of bits inputted from the de-puncturer in a block data unit. The plurality of memory banks store the block data inputted from the distributor. The plurality of switches are connected to the plurality of memory banks respectively. Each switch outputs block data stored in one memory bank. Each decoding unit is connected to a part of switches. Each decoding unit performs the viterbi decoding algorithm about block data and outputs a part of block data.
