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
