Secondly, according to the spectral correlation theory of second order cyclostationary processes, maximumlikelihood filters are used to estimate the cyclic spectra. By estimating the crossspectra of the two frequency shifted versions of cyclostationary signal, the cyclic spectra can be obtained. The analysis effective bandwidth of maximumlikelihood filters is studied in details. In case of cross-spectra estimation, the analysis effective bandwidth of maximum-likelihood filters is not correct. A new method to calculate the analysis effective bandwidth is presented.

第二，根据二阶周期平稳随机信号的谱相关理论，提出了循环谱密度估计的最大似然滤波器法，即采用最大似然滤波器估计出周期平稳信号的两个频移分量之间的互谱密度，从而得到了循环谱密度的估计；对最大似然滤波器的有效分析带宽做了详细的分析，指出了在互谱密度估计时以往的有效分析带宽不正确，并提出了互谱密度估计时的有效分析带宽的新的计算方法。

The results showed that the echolocation calls of the leaf-nosed bats were constant frequency-frequency modulation signals with 2-3 harmonics and the second one among these three harmonics was its dominant frequency. The constant frequency components of three harmonics (Mean±SD, n=18 ) were 33.3±0.2 kHz, 66.5±0.3 kHz, and 99.4±0.5 kHz, respectively. In examined FTCs of 72 IC neurons, their Q 10 -dB values ranged from 0.5 to 95.4 (9.2±14.6) and the neurons whose best frequency around the dominant frequency had sharp frequency tuning.

The proposed scheme distinguishes real-time traffic and non-real-time traffics, and reduces the bandwidth assigned to non-real-time call connections to provide quality of service to real-time call connections if necessary. If there were not enough free bandwidth, the existing multimedia calls could gracefully. contribute a few bandwidth to decrease the CBP and CDP while they were still at an acceptable quality degradation level.

其次讨论了区分实时和非实时业务的带宽预留的呼叫接纳控制算法，对多种媒体业务分类与特性进行了描述并给出了仿真模型；在此基础上提出了一种新颖的基于测量网络状态的动态呼叫接纳控制算法，该算法通过限制实时业务的切换呼叫掉线率低于设定的门限值，并且周期性地调整预留带宽大小以适应快速变化的网络负载状态。

The dequeue attributes include minimum bandwidth, maximum bandwidth, excess bandwidth, and priority, wherein each of the queues has one or more of the dequeue attributes defined.

出队属性包括最小带宽、最大带宽、额外带宽和优先级，其中每个队列被定义了一个或多个出队属性。

Fast bandwidth for the application of the family, but also quite optimistic about the industry,"the development of broadband in the world's best countries - Japan's practice, to provide bandwidth for the bandwidth and then to develop more applications, In fact, as long as it is to provide high-speed data, voice, video services, reflect the triple play of services, users can bring."

对于百兆带宽下的家庭应用，也有业内人士颇为乐观，"以世界上发展宽带最好的国家--日本的做法来看，先提供带宽，然后再为这些带宽开发出更多的应用，事实上，只要是提供高速数据、语音、视频服务，体现三网融合的业务，就可以带来用户。"
