摘要翻译:
在新兴的第五代(5G)无线网络中,毫米波(mmWave)频段在满足不断增长的高数据速率和容量需求方面的潜力是显而易见的。由于mmWave系统需要使用具有高度聚焦波束的高定向天线来克服该频段中严重的路径丢失和阴影,因此mmWave无线网络中的信号传播特性可能不同于当前的网络。受这种传播特性影响的一个因素是干扰行为,它也受到多个用户同时使用频谱的未许可部分的影响。因此,考虑到mmWave频段的传播特性,我们提出了一种适用于5G mmWave应用的空间-频谱干扰模型,分别在许可和非许可mmWave频段存在阻塞和干扰源的泊松场情况下。因此,计算网络的平均误码率。通过仿真验证了本文的结果。

英文摘要:
The potential of the millimeter wave (mmWave) band in meeting the ever growing demand for high data rate and capacity in emerging fifth generation (5G) wireless networks is well-established. Since mmWave systems are expected to use highly directional antennas with very focused beams to overcome severe pathloss and shadowing in this band, the nature of signal propagation in mmWave wireless networks may differ from current networks. One factor that is influenced by such propagation characteristics is the interference behavior, which is also impacted by simultaneous use of the unlicensed portion of the spectrum by multiple users. Therefore, considering the propagation characteristics in the mmWave band, we propose a spatial-spectral interference model for 5G mmWave applications, in the presence of Poisson field of blockages and interferers operating in licensed and unlicensed mmWave spectrum. Consequently, the average bit error rate of the network is calculated. Simulation is also carried out to verify the outcomes of the paper.
