摘要

频谱感知是认知无线电(CR)系统的一项重要功能，它通过频谱共享实现无线系统中更有效的频谱利用。本文考虑了一种基于时域符号相互关联(TDSC)技术的频谱感知CR系统，并研究了其在移动WiMAX标准中的应用，对TDSC方法进行了解析解释，并用仿真得到的数值结果进行了说明。

Using OFDM pilot tones for spectrum sensing with applications to mobile WiMAX

Spectrum sensing is an important functionality for cognitive radio (CR) systems and enables more efficient spectrum utilization in wireless systems through spectrum sharing. In this paper, we consider a CR system that uses spectrum sensing based on the Time-Domain Symbol Cross-correlation (TDSC) technique, and study its application in the context of the mobile WiMAX standard for which the TDSC method is explained analytically and illustrated with numerical results obtained from simulations.
