CRC-based adaptive halting turbo decoder and method of use

摘要

A CRC-based adaptive halting turbo decoder applies a CRC code to identify internally generated information sequences. The information sequences are encoded with the CRC code and can be substantially identified by only the parity part. New information sequences are generated during each iteration and used to estimate the state of the convergence. The CRC-based adaptive halting turbo decoder is halted when the information sequences generated in two contiguous iterations produce identical parity bits. Memory storage requirements for the adaptive halting are reduced since only the parity bits are stored.
