this is another gmm training matlab source code. it use k-means for initialization of parameter before trainig, not LBG algirhtm. so it is very helpful for GMM training

说明：  ASK调制 可用于MATLAB中实现2ASK 4ASK调制 仿真通道(Ask modulation and demodulation)

改进的育群算法，结合SVM用于语音识别,,识别率明显提高(Improved fertility swarm algorithm, combined with SVM for speech recognition)

NExt法(自然激励技术法)模态参数识别预处理(The NExt France (natural incentive Technology Act) modal parameter identification pretreatment)

实现快速贝叶斯算法,先验超参数分布不再使用高斯函数而是用拉普拉斯函数代替(Fast Bayesian algorithm, a priori super-Gaussian parameter distribution is no longer used but with the Laplace function instead)

利用matlab写的较基本的arnold加密与相应解密算法，其中的key可以任意改之，但加密次数不宜太多，最好在100次以内(Use matlab to write the basic Arnold encryption and decryption algorithm, one of the key can be arbitrary change, but the number of encryption shoulds not be too much, best within 100 times)

说明：  主要是用于提取超声导波的时域特征，例如偏度参数、峰度系数、形状系数、离散系数等等(Time Domain Characteristics for Extracting Ultrasound Guided Waves)

LMS由美国斯坦福大学的Widrow和Hoff在研究自适应理论时提出的，由于其容易实现而很快得到了广泛应用，成为自适应滤波的标准算法。 (LMS Widrow of Stanford University by the United States and Hoff adaptive theory put forward in the study, because of its easy to implement and will soon be widely used as a standard adaptive filtering algorithms.)

做出一个动态图形,在matlab中生成一幅可以动态显示的图形，效果还好，值得一看(make a moving picture)

几乎包括所有的OFDM所需要的源程序,包括信道模型，循环前缀等源代码(inculding almost all OFDM source code )
