摘　　要：提出了一种新的适用于基于TDMA的无线ATM网络MAC协议 ,即改进型动态时隙分配多址协议 .通过在预留阶段直接使用预先存储的正交码 ,避免了MAC协议对硬件的依赖 .RR时隙的使用减少了因重新预留所引起的碰撞 .仿真结果表明此协议适用于高速无线ATM网络 。Presents the media access control (MAC) protocol for TDMA based wireless ATM network, an improved dynamic slots allocation multiple access protocol, in which, the dependence of MAC on hardware is avoided with the use of orthogonal codes that are stored in a certain memory in the mobile terminals and the base station in advance in the reservation phase, and in addition, a RR slot is used to reduce the collision of the reservation packets caused by re reservation request, and concludes from the results of simulation that this new protocol is suitable for high bit rate wireless ATM networks, and enjoys good performances.
