摘　　要：ATM技术是基于信道质量非常好的光纤信道提出的。在野战地域通信网战术无线环境下 ,为了采用 ATM技术来支持综合业务 ,并为各类业务提供相应的 Qo S保证 ,必须对 ATM信元结构做出一定的优化改造。首先介绍了几种被采用的无线 ATM信元结构改造方案 ,然后针对野战地域通信网战术环境 ,对信道丢失率和净荷差错率进行理论分析 ,并结合流行的网络级仿真工具 OPNET进行仿真研究 ,得到了有参考意义的结论。In order to support integrated services and provide QoS guarantee to various services in battlefield area network tactical wireless environment, it is necessary to introduce ATM technology into tactical environment. However, ATM technology is initially presented based on fiber optical channel. It could not work effectively wihout error correction schemes. Firstly, several wireless ATM cell structure schemes are presenred. Based on the environment of battlefield area network, the cell loss ratio and payload error ratio of the several ATM cell structure schemes are compared theoretically. Then a simulation is performed to verify the results obtained in the theoretical analysis and finally a conclusion is drawn.
