    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.

    摘要: Techniques to increase the capacity of a W-CDMA wireless communications system. In an exemplary embodiment, early termination (400) of one or more transport channels on a W-CDMA wireless communications link is provided. In particular, early decoding (421, 423) is performed on slots as they are received over the air, and techniques are described for signaling (431, 432) acknowledgment messages (ACK's) for one or more transport channels correctly decoded to terminate the transmission of those transport channels. The techniques may be applied to the transmission of voice signals using the adaptive multi-rate (AMR) codec. Further exemplary embodiments describe aspects to reduce the transmission power and rate of power control commands sent over the air, as well as aspects for applying tail-biting convolutional codes (1015) in the system.
