文章展示了基于高斯混合模型的语音频谱预测方法。频谱预测可能在传包过程中预防丢包这方面起到大作用。期望最大化算法用两倍或三倍的连续语音因素来测试模型。模型被用来设计第一，儿等指令预测量。预测表用频谱分配状态来估计并和一个简单的参考模型对比。最好的预测表得到一个平均频率扭曲值是0.46dB小于参考模型(This paper presents methods for speech spectrum prediction based on Gaussian mixture models. Spectrum prediction may be useful in a packet transmission system where the sensitivity to packet losses is a major problem. Models of speech are trained by the Expectation Maximization algorithm using pairs, triples etc. of consecutive cepstral vectors. The models are used to design first, second etc. order predictors. The prediction schemes are evaluated using the spectral distortion criterion and compared to a simple reference method. The best prediction scheme obtains an average spectral distortion that is 0.46 dB less than for the reference method. )

这是一本关于雷达系统仿真的matlab英文书，非常系统的介绍了雷达系统的仿真。(This is the one on the radar system simulation matlab English books, very systematic introduction to the radar system simulation.)

用Romberg法求积分计算准确，while循环次数一般不超过10，运算较为方便、快捷；计算之前，需要给出所求函数的表达式，积分上限和下限以及误差范围。运用MATTLAB程序求解积分省时、省力。(用Romberg法求积分计算准确，while循环次数一般不超过10，运算较为方便、快捷；计算之前，需要给出所求函数的表达式，积分上限和下限以及误差范围。运用MATTLAB程序求解积分省时、省力。用Romberg法求积分计算准确，while循环次数一般不超过10，运算较为方便、快捷；计算之前，需要给出所求函数的表达式，积分上限和下限以及误差范围。运用MATTLAB程序求解积分省时、省力。自动检测中英文中译英英译中百度翻译. 翻译结果（中 > 英）复制结果 Using Romberg method for integral calculation accuracy, while cycle number less than 10, operation more convenient, fast calculation before, given the need for function expression, integral upper and lower as well as the error range.
