摘要： 研究了认知无线电用户采用序贯检测时认知系统吞吐量的优化问题。首先给出了认知无线电中序贯检测器的形式;然后在充分保护主用户的条件下，建立了系统吞吐量的数学模型，并利用最优化理论证明了存在唯一最优的参数设置，它可使吞吐量达到最大;最后给出最优参数的搜索方法。

Abstract: I}he throughput optimization of cognitive radio based on sequential detection was studied. The form of sequential detection in cognitive radio was given, then the mathematical model of throughput was established with the constraint that the primary users arc sufficiently protected. Furthermore, it is proved that there is a unique optimal paramcter setting which achieves the maximal throughput by optimization theory. At last, a searching method was given to oblain the optimal parameter setting.
Key words: Cognitive radio, Spectrum detection, Sequential detection, Sensing time, Throughput
