摘要

提出了一种用于码本设计的改进粒子群优化方案。通过对训练向量进行排序，选择初始码本增强搜索的多样性，并加入停滞判断代数防止算法陷入局部最优。仿真结果证明了改进方法的合理性。

Codebook design of vector quantization based on improved particle swarm optimization

An improved particle swarm optimization scheme for codebook design is proposed in this paper. By sorting the training vector, we select the initial codebook to enhance the diversity of search, and add stagnant judging algebra to prevent the algorithm falling into a local optimum. The simulation results prove that the improved method is reasonable.
