Abstract

Spectrum sharing, in which multiple wireless systems share the same radio resources, has been considered to improve frequency utilization efficiency. As a spectrum sharing without control signals, a technique that observes the usage of radio resources, called channel occupation ratio, used by other systems and selects a vacant channel has been considered. However, previous studies have simplified the model of the interfering system, which is different from the real environment. In wireless communications, fluctuations in received power occur due to shadowing caused by the location and the surrounding environment. Previous studies have not clarified the effect of received power fluctuation due to shadowing on observing the occupancy rate. This letter formulates the effects on the observation results of received power fluctuations due to the location of interfering stations and shadowing. Computer simulations with randomly placed interfering stations and shadowing environments show that the proposed formulation almost matches the observed results.
评估阴影对频谱共享接入信道观测的影响
频谱共享是指多个无线系统共享相同的无线电资源,它被认为可以提高频率利用效率。在没有控制信号的频谱共享中,有一种技术被认为是观测其他系统使用的无线电资源(称为信道占用率),并选择空闲信道的技术。然而,以往的研究简化了干扰系统的模型,这与真实环境不同。在无线通信中,由于位置和周围环境造成的阴影,接收功率会发生波动。以往的研究没有阐明阴影导致的接收功率波动对观测占用率的影响。本文阐述了干扰站位置和阴影导致的接收功率波动对观测结果的影响。随机放置干扰站和阴影环境下的计算机模拟表明,所提出的公式与观测结果基本吻合。
