Method to improve diversity gain in a cooperative spectrum sensing network
摘要：
A cooperative sensing technique (300) operates by selecting a group of subscribers (302) from a secondary system, measuring a cooperative sensing metric (306) and then using the metric to identify an achievable spatial diversity gain for the group of selected subscribers (308). Once an achievable spatial diversity gain is determined for the group (308/412), it is compared to a required spatial diversity gain (310), and if the condition is met at (310), the validated group can begin spectrum sensing (314) to identify a vacant/suitable channel for operation. If the achievable spatial diversity gain is insufficient, then a new group of users is selected (312) within the secondary system and the process repeats itself.

协作感测技术（300）通过从次系统选择一组订户（302）来操作，测量协作感测度量（306），然后使用度量来识别所选择的用户组（308）的可实现的空间分集增益 ）。 一旦为组确定可实现的空间分集增益（308/412），则将其与所需的空间分集增益（310）进行比较，如果在（310）满足条件，则验证组可以开始频谱感测（314 ）来确定一个空的/合适的操作通道。 如果可实现的空间分集增益不足，则在辅助系统内选择一组新的用户（312），并且该过程重复。
