退火粒子群优化算法（SAPSO），matlab代码，仅供学习(Annealing particle swarm optimization (SAPSO), matlab code, only to learn)

说明：  128QAM调制仿真的星座图。matlab源文件。(Simulation 128QAM modulation constellation diagram. matlab source file.)

this Program utilized a new method for generation codebook in Hidden Markov Models (HMM). Hybrid HMM and neural networks have been applied to improve recognition in speech processing.

置信传播(belief propagation,BP)算法的计算复杂度较高，且变量节点和校验节点间信息传递的信息可靠，但是迭代的实现，就最大似然算法来说，验证其提高译码性能的特点。 (Belief propagation (belief propagation, BP) higher computational complexity of the algorithm, and reliable information between variable nodes and check nodes of information transmission, but the realization of the iteration, the maximum likelihood algorithm, the verification of its improved decoding performance characteristics.)

simulate two channel tdm_pcm using matlab

OFDM仿真程序MATLAB 接收端采用的算法和程序流程与发送端发送的OFDM符号的帧结构有关系。具体的帧结构，以及定时估计，频偏估计，剩余误差跟踪的算法可参考算法说明文档(MATLAB simulation program OFDM receiver algorithm and procedures used in processes and the sending end to send the frame structure of OFDM symbols are.
