System and method for unsynchronized cooperative spectrum sensing in cognitive radio nodes |
摘要 |
System and method for unsynchronized cooperative spectrum sensing in cognitive radio nodes. A method comprises receiving spectrum sensing information from a plurality of communications nodes, computing for each communications node in the plurality of communications nodes, a likelihood ratio based on spectrum sensing information provided by the communications node, combining the likelihood ratios, and computing a decision value based on the combined likelihood ratio. Each communications node determines its respective spectrum sensing information at a time unrelated to times when other communications nodes determine their spectrum sensing information. |
