印度TV白色空间的定量评估
Quantitative Assessment of TV White Space in India
摘要：
在文献中，许可但未使用的电视（TV）频带频谱被称为TV空白空间。超高频（UHF）电视频段频谱具有很好的无线电波传播特性。印度UHF电视频带中的电视空白空间的量是令人感兴趣的。本文对印度四个地区（除北部外）470- 590 MHz频段的电视空白频段进行了全面的定量评估和估计。这是印度首次全面评估电视空白空间。使用两种方法计算这四个区域中每单位面积的平均可用TV空白空间：（i）主要（许可）用户和次要（未许可）用户的观点;以及（ii）美国联邦通信委员会的规定。通过这两种方法，在UHF电视频段的平均可用电视空白空间被证明是超过100 MHz！还描述了一种电视发射机频率再分配算法。基于空间复用的思想，提出了一种电视信道分配方案，该方案在使用最少的电视信道进行跨四个区域的传输的同时，对电视接收机的干扰较小。基于这一重新分配，它被发现，四个电视频带频道（或32兆赫）足以提供现有的UHF电视频带覆盖在印度。
英文摘要：
Licensed but unutilized television (TV) band spectrum is called as TV white space in the literature. Ultra high frequency (UHF) TV band spectrum has very good wireless radio propagation characteristics. The amount of TV white space in the UHF TV band in India is of interest. Comprehensive quantitative assessment and estimates for the TV white space in the 470-590MHz band for four zones of India (all except north) are presented in this work. This is the first effort in India to estimate TV white spaces in a comprehensive manner. The average available TV white space per unit area in these four zones is calculated using two methods: (i) the primary (licensed) user and secondary (unlicensed) user point of view; and, (ii) the regulations of Federal Communications Commission in the United States. By both methods, the average available TV white space in the UHF TV band is shown to be more than 100MHz! A TV transmitter frequency-reassignment algorithm is also described. Based on spatial-reuse ideas, a TV channel allocation scheme is presented which results in insignicant interference to the TV receivers while using the least number of TV channels for transmission across the four zones. Based on this reassignment, it is found that four TV band channels (or 32MHz) are sufficient to provide the existing UHF TV band coverage in India.
