【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.更多还原
