| 摘要 |
A method of decoding a signal that has been encoded by a tail-biting code based on at least one encoding parameter is disclosed. The method is suitable for use in a communication device and comprises receiving (510) the signal, performing (520) a first decoding attempt of the signal based on a first set of starting state metrics and a first encoding parameter hypothesis, the first decoding attempt resulting in a first set of ending state metrics. The method further comprises performing (520), if the first decoding attempt fails, a second decoding attempt of the signal based on a second set of starting state metrics based on the first set of ending state metrics and a second encoding parameter hypothesis different from the first encoding parameter hypothesis. Corresponding arrangement, communication device, and computer program product are also disclosed. |
