摘要
研究了认知无线电位置意识功能,重点讨论了自适应TOA(Time of Arrival)定位技术,推导了可采用Under-lay频谱接入定位方式的判决条件,提出了增加Underlay方式成功定位几率的措施。数值计算结果验证了提出的判决条件以及增加Underlay方式成功传输几率的措施的有效性。
Location awareness for cognitive radios is studied, with a focus on the adaptive TOA （Time of Arrival） positioning technique. The decision criteria for positioning via underlay spectrum access is derived, and the ways to improve the success rate under underlay spectrum access positioning are proposed. Numerical results validate the derived decision criteria and the proposed measures.
