Abstract

A physical layer performance evaluation of WLAN (IEEE 802.11b) and Zigbee (IEEE 802.15.4) receivers in the presence of impulsive noise is presented. Broadband impulsive noise is modeled as a Symmetric Alpha-Stable process. The parameters of the impulsive noise model are estimated from data recorded from an electricity transmission substation (ETS). The results show that the performance degradation of the Zigbee receiver is small whilst the WLAN receiver may suffer more significant degradation.

变电站脉冲噪声环境下无线局域网和Zigbee性能仿真
对存在脉冲噪声的WLAN (IEEE 802.11b)和Zigbee (IEEE 802.15.4)接收机进行了物理层性能评估。宽带脉冲噪声被建模为一个对称的α稳定过程。脉冲噪声模型的参数是根据一个输变电所记录的数据估计出来的。结果表明,Zigbee接收机的性能下降幅度较小,而WLAN接收机的性能下降幅度较大。
