Examples in Context

  1. It uses two improved parameters : mutual information and log likelihood ratio.
  2. In the sequential density evolution analysis, we obtain the calculation expression of information density evolution by analyzing the probability measure based on the log likelihood ratio measurement.
  3. At the same time, the theoretic basis of the algorithm is given and precondition for the validity of the log likelihood ratio is derived.
  4. Thirdly, the principle of turbo-code coder and decoder are presented. The turbo-code decoder produces bit available reliability information expressed as a log likelihood ratio, which includes the channel information.
  5. Turbo coder is composed of tow or more RSC coder connected through several interleavers. The Turbo decoder output is not bit stream, but the log likelihood ratio of each bit.
