在matlab中cceps 函数使用,举例说明
help cceps
就有这个函数的实例和使用方法了.

再答： 好老的版本了。你换成2010吧。我的2010就有例子，还有比较详细的说明。 以下是我matlab2010的帮助部分说明。你参考一下吧。 CCEPS(X) returns the complex cepstrum of the real sequence X using Fourier transform as in its definition [1]. The input is altered to have no phase discontinuity at +/- pi radians by the application of a linear phase term (that is, it is circularly shifted (after zero-padding) by some samples if necessary to have zero phase at pi radians). The program follows the procedure used in [2] [XHAT,ND] = CCEPS(X) returns the number of samples ND of (circular) delay added to X prior to finding the complex cepstrum. [XHAT,ND,XHAT1] = CCEPS(X) returns the complex cepstrum in XHAT1 using an alternate factorization algorithm developed in [3]. The first element in the data sequence cannot be zero. CCEPS(X,N) zero-pads X to length N, and returns the length N complex cepstrum of X. EXAMPLE: Use CCEPS to show an echo. Fs = 100; t = 0:1/Fs:1.27; s1 = sin(2*pi*45*t); % 45Hz sine wave sampled at 100Hz % Add an echo of the signal, with half the amplitude, 0.2 seconds after % the beginning of the signal. s2 = s1 + 0.5*[zeros(1,20) s1(1:108)]; c = cceps(s2); plot(t,c) title('The peak at 0.2 shows the echo'); See also icceps, rceps, hilbert, and fft.
