Research on a Variable Bit Rate for LD CELP Speech Coding

一种可变速率的LD-CELP编码的研究

You cannot use variable bit rate encoding with uncompressed video.

对未压缩视频不能使用可变比特率编码.

We first point out the limitations of currently standardized IS 95 variable bit rate scheme. Then we analyze the orthogonal characteristics between the Walsh functions of different periods, and present the method of properly choosing Walsh function for each channel in order to support multi rate transmission.

文中首先指明了现有IS－95系统多速率传输的局限性，然后通过分析不同周期离散Walsh函数的正交特性，指出如何通过适当分配各个用户信道的Walsh码，达到支持多速率业务的目的。

Multimedia traffic has become the chief source of ATM network gradually with the development of broadband network and digital compression technology, and most of them are transmitted through variable bit rate ( VBR) mode.

宽带网络及数字压缩技术的不断发展致使多媒体业务逐渐成为ATM网业务的主要来源，其大部分都采用变比特率方式（VBR）进行传输。

A new service class was added in the proposed algorithm to meet the delay requirement of rt-VBR traffic, while scheduling nrt-VBR ( non-real-time variable bit rate) traffic effectively.

该算法在DWRR的轮询过程中插入1个新的服务优先等级，从而有效地保证变速率实时多媒体业务的时延要求，并且也可有效地调度非实时业务。
