Codeword Search Based on Genetic Algorithm

2014 
In the paper, an iLBC codec based on genetic algorithm is proposed. In the iLBC speech codec, the fully searching algorithm is used to codeword search. Genetic algorithm, which based on adaptive probabilistic search for global optimization, can reduce the number of searching effectively, and the parameters can be searched out more quickly. The thoughts of combine speech codec with genetic algorithm and the result of simulation are presented, and the feasibility of the genetic algorithm to reduce iLBC Codec device codeword searches is verified.
