复倒谱  一个函数的傅里叶变换的对数的傅里叶反变换。对褶积信号的线性分离作用,在实际信号处理中很有用处,例如可应用于通信、建筑声学、地震分析、地质勘探和语音处理等领域。尤其在语音处理方面,应用复倒谱算法可制成同态预测声码器系统,用于高度保密的通信。    在离散信号x(n)情况下,用z变换表示复倒谱,可以写作    复倒谱可以利用同态系统中一种特定的特征系统来求得,如图所示。为了区别于用一般方法所求得的频谱(spectrum),将spectrum这一词前半部(spec)字母顺序颠倒即成cepstrum,根据词形定名为倒谱。又因频谱一般为复数谱,故称为复倒谱。为了说明复倒谱的性质,假设已知两信号x1(n)和x2(n)相褶积而得到的时间函数x(n),对它们分别求其离散傅里叶变换,写作  X(ω)=DFT[x(n)]  X1(ω)=DFT[x1(n)]  X2(ω)=DFT[x2(n)]  按上述定义,可得到如下关系式  =IDFT{log[X(ω)]}       =IDFT{log[X1(ω)]}+IDFT{log[X2(ω)]}  由此可见,通过复倒谱的运算可将x1(n)和x2(n)的褶积关系变换为相加关系,再采用一般线性系统对它们进行滤波处理。
