白色空间设备（WSDs）接入UHF TV频段的英国和欧洲框架是基于来自白色空间数据库（WSDBs）的指示的可用性，该数据库指定了特定位置的最大允许WSD辐射功率电平。这些水平的计算方式，以便提供保护的数字地面电视（DTT）服务方面的最大允许降级的DTT位置概率。本文的贡献是双重的。首先，我们提出了一种方法用于DTT定位概率的计算，这大大提高了通常用于此目的的技术的准确性。其次，我们提出了一种新的方法来计算最大允许的WSD EIRP，受到目标的位置概率退化。我们表明，尽管其计算效率低，该方法产生的结果相比，通过蛮力蒙特卡罗模拟产生的。这两种技术都适用于电视白色空间数据库的实现。
The UK and European framework for access to the UHF TV band by white space devices (WSDs) is predicated on the availability of instructions from white space databases (WSDBs) which specify location-specific maximum permitted WSD radiated power levels. These levels are calculated in such a way so as to afford protection to the digital terrestrial TV (DTT) service in terms of a maximum permitted degradation in DTT location probability. The contribution of this paper is two-fold. Firstly, we present an approach for the calculation of DTT location probability which improves considerably on the accuracy of the technique commonly used for this purpose. Secondly, we present a novel methodology for the calculation of the maximum permitted WSD EIRP, subject to a target degradation in location probability. We show that, despite its low computational efficiency, the methodology generates results which compare favorably with those generated via brute-force Monte Carlo simulations. Both presented techniques are suitable for implementation in TV white space databases.
