摘　　要：将跨层机制应用到MIMO—OFDM系统中能更好地适应未来通信网络中存着多种服务的环境，该文详细地分析了跨层设计的原理，将物理层和链路层的联合优化机制与多载波系统和空时编码相结合，对多径衰落信道下未编码系统中物理层与链路层联合优化进行了分析。Cross-layer mechanism applied in MIMO-OFDM system can better adapt to the environment ot the future commumcation networks in which many kinds of services exist. In this paper, the principle of cross-layer design is analyzed detailedly, and combining the physical layer and the link layer joint optimization mechanism with the multi-carrier system and the space-time coding system, the joint optimization between physical and lnik layers in Non-Coding System under the multipath fading channel is analyzed.
