  • Method for decoding data sequence encoded with aid of binary convolution code
    Patent number: 7143334
    Abstract: A data sequence consisting of K information bits that has been encoded with the help of a binary convolution code is decoded using a MaxLogMAP algorithm. In a first calculation operation, metric values are calculated accurately in a forwards and backwards direction in a trellis diagram and only some of the values are stored in a memory as interpolation points for an additional calculation operation. The additional calculation operation uses the interpolation points to accurately calculate the metric values that lie between the interpolation points of the first calculation operation. Soft output values are accurately determined for decoding after n operations.

  • Arrangement for data processing
    Patent number: 6377797
    Abstract: A number of data processors, that each contain at least one processor, a memory and an interface, are provided in the inventive arrangement. The arrangement further comprises at least one digital transmitter that is connected to the data processors via a program bus and sends program code over the program bus, only parts thereof being stored in a respective data processor. The arrangement is particularly suited for transcoder units in mobile radiotelephone systems wherein a number of encoding methods are utilized or a switching in the sense of an adaptive multi-rate encoder ensues.
