摘　　要：文中在研究移动通信系统吞吐量性能的基础上,提出一种联合自适应编码调制技术和自适应帧长技术的自动要求重传方案。该方案根据当前无线物理信道状态选择合适的编码调制方式和帧长进行传输,并对错误帧进行选择性重传,在保证系统误帧率性能的同时提高链路吞吐量。实验结果表明,该方案能够有效提高系统链路吞吐量性能。Based on the analysis of the throughput performance in mobile communication systems, an Automatic Rrepeat Request (ARQ) scheme was proposed combining with Adaptive Modulation and Coding (AMC) and adaptive frame length techniques. This scheme chose the most suitable modulation, coding and frame length to transfer data, and retransmitted those frames which were received inaccurately. It could improve the throughput for a desired level of Frame Error Ratio (FER). Simulations results verify its enhancement to the throughput performance of the system link.
