Cepstrum Transform on TMS320C55x Series DSP with DSPLIB

Using cepsturm characteristics to test signal power spetrum for periodic signal is benefical to further analyse and recognize fault frenquency.Cepstrum algorithm was achieved in fixed DSP TMS320C55x.Using DSP library on TMS320C55x DSP,the speed and the reliability of the signal processing were improved and the developing speed was quickened.The realization of the cepstrum algorithm was studied using DSP library.
