1, speaker recognition as a kind of biological authentication technology, according to the report in speech waveforms is physiological and behavioral characteristics to the speech parameters, the identity of the speaker automatic identification technology as a. This paper through analyzing the characteristics of speech characteristics parameters of basic and speaker recognition method, has realized the MFCC parameters by using the dynamic time GuiZheng algorithm with text related speaker recognition system, then changed the extraction of characteristic parameters, MFCC parameters in a order difference for characteristics, improve the system recognition rate.
2, this paper video sequence, the sports face is proposed based on video integral frame difference and combined with the face skin color information of face of movement on algorithm testing. This method firstly in the continuous frame difference in image sequences two or three
3, speech enhancement refers to extract from speech with noise of as much as possible the purity of the original speech signal, it aim to have two: one is to improve the definition; speech Two is to improve the speech intelligibility. Common speech enhancement algorithm has wiener filtering method, noise reduction of XiaoFa, such as spectrum method. One has to adapt to spectral subtraction SNR range, the method is simple, easy to real-time processing wait for an advantage, but for speech enhancement has obvious "music noise" defects. This paper based on improved realized a spectral subtraction speech enhancement algorithm. Aimed at the defects of traditional spectral subtraction speech endpoint detection combination, the combination of recursion smooth methods to estimate noise spectrum. First to the speech signal with noise, and the pretreatment on FFT spectrum, ask in frequency conversion
4, direct sequence spread spectrum communication technology because of latent good, strong anti-jamming capability, fight multipath interference, easy to realize the advantages and cdma wireless data communication, mobile communication and other areas to be more widely. This paper is based on the MATLAB simulation of direct sequence spread spectrum communication system. After the sender of digital signal input information, first by spread spectrum code generator generated spread spectrum yards digital signal to the detuning sequence modulation signal spectrum of the signal, the detuning send out again to radiofrequency modulated. In the receiver received signals were demodulated by local produce, then with the sender of the same spread spectrum yards sequence to relevant solution extender. From the results that even in SNR greatly circumstance, still can normal communication, and verifies the direct sequence spread spectrum tong ?
