进而判断并逼近最终目标用户

直至确定认知用户的频率使用权。仿真结果和理论分析进一步验证了所提方案的可行性。

Abstract

A frequency sense solution based on the double-station cooperation and multi-hop tracing localization was presented for resolving the hidden and exposed problems in the dynamic spectrum resource management so as to improve reliability and efficiency of the frequency sense and increase the utilization of spectrum.In this scheme

the secondary user could detect primary user’s existing by an improved centroid localization algorithm cooperated with a known position user.The detailed steps were proposed

the simulation results were discussed and the performance of the tracing localization was analyzed.
