Abstract
Since iterative decoding of turbo codes or SCCC outputs provisional decoded result and likelihood information in the course of the decoding process, effective use of this makes it possible to implement interference cancellation without marked increase in the amount of operations for decoding. For this purpose, decoding of a plurality of turbo code signals or SCCC blocks interfering with one another is implemented in parallel so that iterative decoding is performed making use of the decoded data and likelihood information obtained as the transitive decoding result of turbo codes or SCCC, to decode other blocks.
