Abstract :
The soft-output Viterbi algorithm was applied to DFH system, using the pertinence of the frequency transition. And A serial iterative structure is present, combined with an outer codec. The simulated result shows that compared with the conventional DFH demodulation algorithms, the performance improves obviously.
