The article introduces the channelization technology in WCDMA digital mobile communication system.

本文主要介绍了在WCDMA数字移动通的化技术。

The basic idea is control channel backoff from low power to high power，data channel “backoff” from high to low.

基本思想是控制功率由大小退避，数据功率由小大“退避”。

The simple comparison is made between Integrated Server Digital Network User Part (ISUP) and Telephone User Part (TUP) in this paper.

对公共令的综合业务数字网用户部分(ISUP)和电话用户部分(TUP)进行了简单的比较。

Analyzing fixed channel and dynamic channel we obtained the substantive capacities and brought them into an inhibitable equation for channel allocation proportion.

通过分析动态和固定得各自的独立容量，将其联立作为分配比例的制约方程。

In the HFC network, the funnelling effect of noise is the main restrict matter of raising the rate in the up stream channel.

HFC网络上行的漏斗噪声是制约上行高传输速率的主要原因。

It shows that this kind of device can be tuned hundreds of nanometers.It can demultiplex any channel in all-wave fiber WDM in the future.

分析表明，它的调谐量可以达数百纳米，有望在将来的全波光纤WDM对所有进行解复用。

The blind equalization algorithm is “equanimous” and the characteristic of convergence is not influenced by distortion of channel, it is fit for equalizing deep attenuation channel.

该算法具有镇定性，其收敛性能不会受失真的影响，适用于均衡衰落性严重的。

Based on the experiment it is validated that the system load would impact the inhibitable equation, that is, the certain load would make a corresponding proper allocation proportion.

通过实验进一步验证了制约方程受负载的影响，即确定的负载可以对应最佳的分配比例，按照该比例分配能够得最大的容量。

This article unifiesthe letter source and the channel coding proposes in one kind of videofrequency picture based on the letter source and the channel encodedvector data hideaway method.

本文结合源和编码出一种视频图像基于源和编码的矢量数据的隐藏方法。

In this paper, the authors described the decimal system encryption based on AES and its implementation in detail, and discussed a kind of encryption principle suitable for trustless channel.

详细描述了基于AES的十进制加密算法的实现过程和一种适合于不可靠(预付费与终端之间的通实现非接触无介质代码传送)的加密算法实现原理。
