使用matlab仿真hitran，用以计算气体吸收系数计算(Use matlab simulation hitran, to calculate gas absorption coefficient calculation)

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。 ( On the basis of study of WiMfAX and SIP, a new mechanism using SIP to achieve end-to-end handoff under IEEE802.16e access networks is Ob proposed handoffs, in this thesis. The mechanism adopts a cross-layer design which means that the l}iIAC layer handoff procedure can interleaved with that of the application layer. During the handoff at link )
