RESEARCH_ON_END-TO-END_HANDOFF
说明: 本文在研究IEEE802.16e协议和SIP协议的基础上,提出了利用
SIP解决IEEE802.16接入网络中端到端切换的新方案。该方案采用跨
层切换的设计思想,联合MAC层和应用层SIP协议,在底层链路切换
的同时,完成应用层会话的修改,加快了切换过程,减少了切换时延,
提高了切换成功率。本文基于NS2仿真平台,完成了相应的仿真平台
搭建过程,实现了SIP协议模块和WiMAX协议模块的融合,扩展了SIP
协议模块的部分消息,最终在基于SIP协议模块和WiMAX协议的统一
NS2平台上实现了基于WiMAX接入、支持SIP扩展功能的SIP会话建
立和修改过程。

Under the assumption of absolutely no deterministic knowledge about the signal X(n), i.e., we assume that we know only the average power in the signal. In this case the optimal detector is energy detector or radiometer can be represented as [23]
