摘要:
介绍了CIR混合动态频率选择(DFS)算法.通过对算法的性能分析,提出了算法中一些参数的优化方向.以HIPERLAN/2系统为例进行了仿真.仿真结果表明:对算法参数的合理优化可以使算法充分发挥干扰探测快、频率转换稳定等特点,能够在复杂传播环境下提高WLAN/WPAN的服务质量(QoS).参数优化后的算法可以明显地提高系统的吞吐量.
Abstract:
The CIR blending DFS algorithm is introduced. The optimizing direction of algorithm parameter is presented through algorithm performance analysis. As a concrete application example, this algorithm is simulated in HIPERLAN/2. Simulation results indicate that the parameters reasonably optimized make the algorithm exert its characteristics such as fast finding interference, steady changing frequency. The algorithm with optimized parameter can improve QoS of the WLAN/WPAN system under complicated radiation environment. The system throughput is greatly advanced utilizing the algorithm with optimized parameter.
