The aim of personal mobile communication is communicating with anybody by any information at any time and any place . from anolog to digital , from voice to data , from tdma to fdma to cdma , personal communication is developing rapidly . wcdma is a real 3g communication system , as one of the three mainstream 3g communication system standars . the corn net of wcdma is based on gsm , and wcdma is a real global standar Wcdma是应运而生的全新第三代移动通信系统方案,作为三大主流3g标准之一,是真正意义上的3g ,传输速率完全可以达到384kbps 。 wcdma基于gsm核心网,是真正的全球标准。作为wcdma关键技术之一的基带处理技术,其底层系统的实现是一大难点。
The power control algorithm used in present cdma conunwhcation standar ( for examle , is - 95a and cdma2000 ) is to allocate ophmal power vector for the user in the system sboply by the distance betwen the base station and the user under a predefined norm ( for example , the transmitted power of user or the signalto - interfrence ratio ( sir received by the base station suffice to some a nddrization norm ) , 在现行cdma通信系统标准中(如is - 95a或cdma2000标准) ，采用的功率控制方法是在一定的标准下(如移动用户发射功率或信干比在到达基站时满足某一最低要求标准) ，根据移动台到基站的远近来为系统内用户分配功率的。
Both the internet engineering and internet research task forces ( ietf and irtf ) have been heavily involved in coordinating multicast transport protocol research , development and standar dization . however , congestion control for multicast protocols has emerged as one of the biggest challenges in the large - scale deployment of multicast applications in the internet 在过去几年中，组播传输机制已经成为一个活跃的研究领域， irtf和ietf (因特网研究和工程任务小组)在组播传输协议研究、开发、标准化等方面作了大量的工作。
