Method and system enabling use of white space radio spectrum using digital broadcast signals
摘要：
A system (10) and method (50 or 70) of dynamic allocation of spectrum for a communication device where a UHF band is currently unused for licensed television broadcasting involves determining (51) a location of a user device using GPS or other signals (such as television broadcast signals) received at the user device using signal strength or time distance of arrival of those signals. The method can determine (52) which UHF television broadcast channels are available for use by the user device and determine (53) a maximum allowed transmission power for a given channel based on signal strength for the given channel and on adjacent channels before transmitting (54) the maximum allowed transmission power and location by the user device to a remote server for sharing information. The method can receive (55) polygon endpoints from a television broadcast defining the location of usable reception of the television broadcast.
摘要（中）：

用于对于许可电视广播当前未使用UHF频带的通信设备的频谱的动态分配的系统（10）和方法（50或70）涉及使用GPS或其他信号来确定（51）用户设备的位置 作为电视广播信号）使用这些信号的信号强度或到达时间距离在用户设备处接收。 该方法可以确定（52）哪个UHF电视广播信道可供用户使用，并且基于给定信道的信号强度和在发送之前的相邻信道（54）确定（53）给定信道的最大允许传输功率 ）用户设备向远程服务器发送的最大允许传输功率和位置，用于共享信息。 该方法可以从定义电视广播的可用接收位置的电视广播接收（55）多边形端点。
