Patent ID: 6889353

Claim:
A method for decoding a turbo-coded code word comprising termination bits, the method comprising storing received code word samples in a memory for decoding, the code word sample comprising samples of the actual code word and termination samples corresponding to the termination bits of the code word, applying the samples to a decoder in a sequence required by a code structure, grouping the termination samples according to different code word components, extending one or more interleavers of the code word such that the extension part comprises addresses of systematic termination samples corresponding to termination samples of one or more parity components associated with each interleaver and addresses of extrinsic weight coefficients related to said systematic termination samples, forming an address of ascending order after the samples of the actual code word such that the addresses of the extension part are ascending-order addresses of the extrinsic weight coefficients or of the systematic termination samples corresponding to the termination samples of one or more parities, and executing decoding by using extended ascending address formation or one or more extended interleavers.
