APPARATUS AND METHOD FOR PERFORMING CHANNEL CODING AND DECODING
摘要
<p>A coding apparatus comprises: a means for coding an information bit constituting a transmitted signal with a turbo-SPC system to derive one or more sets of redundancy bits from a set of the information bits; and a redundancy adjusting means for increasing or decreasing the redundancy bits depending on the rate of channel coding specified by a control signal to adjust the ratio of the number of information bits against the number of redundancy bits. At least a part of the redundancy bits increased or decreased by the redundancy adjusting means is the redundancy bits derived from the same set of the information bits.</p>
