发明名称 Soft output decoder for convolutional codes
摘要 Soft output decoding of signals represented by a trellis of block length N divided into windows includes a step of decoding a forward recursion to a location that is I sections from the beginning of the window. An optimum state is detected at the end of the forward recursion. A backward recursion is performed from the determined state at the end of the window back to the beginning of the window to define a set of known backward recursion state metrics. Soft outputs are calculated during the backward recursion using the stored forward recursion state metrics, the backward recursion state metrics, and branch metrics at each state.
