METHOD FOR DECODING A DATA SEQUENCE THAT HAS BEEN ENCODED WITH THE HELP OF A BINARY CONVOLUTION CODE

摘要

the present invention is a binary convolutional code used in the encoding K information bits as a data sequence consisting of the Use MaxLogMAP relates to a method for decoding. In the first calculation operation, only some of the metric values are calculated correctly only in the forward and reverse directions of the lattice diagram and the values are stored as interpolation points for the further calculations in the memory operation. The interpolation points are used for more exact calculation operation to calculate a metric value lies between the interpolated point of the first calculation operation. Soft output values are formed for decoding, the values are determined accurately after the n single operation.
