A New Codebook Design Scheme Based on Ant Colony Clustering

A new improved ant colony codebook design scheme is proposed by adopting frequency sensitivity measure in an original basic ant colony algorithm. The LBG (Linde-Buzo-Gray) codebook design optimization rule is adopted in the new scheme. Since the scheme decreases the probability of choosing the same cell by increasing the distortion measure, the randomization of choosing a cell is increased. The scheme can avoid achieving a local optimization solution and enhance the global search ability. The experiment result shows that the new scheme is more valuable and effective than other schemes in the convergence of codebook design and the performance of codebook.
