Method of decoding an incident turbo-code encoded signal in a receiver, and corresponding receiver, in particular for mobile radio systems

摘要

The quality information representing the conditions of channel state estimation, is determined and compared with predetermined criteria for defining a binary result corresponding to good or bad estimation conditions. A maximum-a-posteriori (MAP) algorithm called log MAP or an approximation of MAP algorithm called Max log MAP is selected dynamically according to the presence of good or bad conditions. An independent claim is also included for receiver.
