摘要： Cognitive radio is a paradigm for wireless communication in which either a network or a wireless node changes its transmission or reception parameters to communicate efficiently avoiding interference with licensed or unlicensed users. This alteration of parameters is based on the active monitoring of several factors in the external and internal radio environment, such as radio frequency spectrum, user behavior and network state.
感知无线电是一种新的智能无线通信技术。它可以感知到周围的环境特征，并自动调整其设备的一些发射和接收参数，从而有效的消除用户间的干扰。此优势基于具有感知能力的设备能够对无线通信系统的内部和外部环境进行侦听，从而能得知诸如频谱的使用情况，用户的通信方式，整个通信网络状态等。
崔曙光教授简介：
Dr. Cui received the B.S. degree in Radio Engineering from the Beijing University of Posts and Telecommunications in 1997, The M.S. degree in Electrical and Computer Engineering from McMaster University in 2000, and the Ph.D degree from Stanford University in 2005. Since June of 2007, he has been an Assistant Professor of Electrical and Computer Engineering, at the Texas A&M University. Prior to that, he was an Assistant Professor in the ECE department at the University of Arizona. For further information please refer to http://www.ece.tamu.edu/~cui/.
