中文摘要：
针对速率自适应算法RADM在瑞利衰落信道下吞吐量低、适用性差的问题,提出了M-RADM算法。通过改变速率决策规则并实时修正统计窗口时间,使短期速率调整机制和长期速率调整机制有效配合,合理地调整了速率。仿真结果表明,在瑞利平坦衰落信道下,M-RADM算法在满足一定误码性能的同时提高了吞吐量。
英文摘要：
Aiming at the low throughput and poor applicability of rate adaptive algorithm RADM in the Rayleigh fading channel, a M-RADM algorithm is proposed. By changing the rate decision rules and revising the statistics window time, the short-time rate adjusted mechanism coordinates with the long-time rate adjusted mechanism effectively, the rate is adjusted adaptively. The simulation results show that the improved algorithm not only satisfies certain bit error ratio, but also can effectively improve the performance of throughput in the rayleigh flat fading channel.
