信道

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

本文介绍了在WCDMA数字移动信系统中信道化技术。

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

基本思想是控制信道功率由大到小退，数据信道功率由小到大“退”。

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

分析动态信道和固定信道得到各自独立容量，将其联立作为信道分配比例制约方程。

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

对公共信道信令系统中综业务数字网用户部分(ISUP)和电话用户部分(TUP)进行了简单比较。

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

HFC网络中上行信道漏斗噪声是制约上行信道提高传输速率原因。

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，它调谐量可以达到数百纳米，有望在将来全波光纤WDM中对所有信道进行解复用。

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，其收敛性能不会受到失真信道影响，适用于均衡衰落性严重信道。

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.

本文结信源和信道编码提出一种视频图像中基于信源和信道编码矢量数据隐藏方法。

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.

实验进一步验证了制约方程受系统负载影响，即确定负载可以对应最佳分配比例，按照该比例分配信道能够得到最大系统容量。

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十进制加密算法实现程和一种适于不可靠信道(预付费系统与终端之间信实现非接触无介质代码传送)加密算法实现原理。
