多小區(qū)無線局域網(wǎng)的系統(tǒng)吞吐率估計(jì)算法

The System Throughput Estimation Method for Multi-cell WLANs

  • 摘要: 在多小區(qū)無線局域網(wǎng)(WirelessLocal AreaNetworks,WLAN)中,由于存在小區(qū)間接入訪問點(diǎn)同頻干擾,以及小區(qū)間同頻用戶干擾,其系統(tǒng)性能與單小區(qū)網(wǎng)絡(luò)具有很大不同.本文提出了支持多種用戶傳輸速率共存、支持用戶非均勻分布的多小區(qū)WLAN系統(tǒng)吞吐率估計(jì)算法.通過對(duì)多小區(qū)WLAN中接入訪問點(diǎn)的布置、信道的配置進(jìn)行仿真,結(jié)果表明即使在存在小區(qū)間同頻干擾的情況下,估計(jì)算法也能得到滿意的吞吐率估計(jì)結(jié)果.
