The experiments show the frame of CGMM-UBM can make better use of the training data and the mixtures of the models are fewer and the efficiency of models training is higher. The CGMM-UBM system also gets better recognition results and is robust to noise. The system is more suitable for the speaker verification with short speech. Since the SVM based fusion is trained with two class data, it has better discriminability and can elaborately reflect the relation between the sub-systems.

实验表明，CGMM-UBM结构能够更为充分的利用训练数据，模型混合度可以较低，并且具有较高的模型训练效率，同时系统也获得了较好的识别性能与噪声鲁棒性，适于短语音情况下的说话人确认。

If you are using the perlin noise function to render an image to the screen, there will come a point when an octave has too high a frequency to be displayable.

如果你正使用柏林噪声函数在屏幕上渲染图象的话，如果倍频频率太高将会使缩成一个点以至于不能显示，这就是因为你屏幕的分辨率不够。

The analysis of simulation result indicates that the CDMA system has much more superior performance on noise-immune; the continuous processing in the part of signal modulation can not improve the efficiency of spectrum in CDMA system; under the situation , making sure that the proximity of the reliability of information transmission to the unsmoothed system, the power of the transmission can decline to 90.5% of the unsmoothed system, the bandwidth of -50dB will decline to almost one half of the unsmoothed system in spread spectrum and dispread spectrum by using continuous WALSH codes.

仿真及分析结果表明：CDMA系统具有更优越的抗噪声性能；信息调制部分的平滑化处理在CDMA系统中不会改善频谱的利用效率；运用平滑化WALSH码进行扩频和解扩时，在保证信息传输可靠性与非平滑化系统接近的情况下，能够将发射功率降低到非平滑化系统的90.5%，-50dB带宽减小到非平滑化系统的一半左右，这有利于降低对临近频段的干扰，提高频谱的利用效率。
