Compared with singleuser spectrum sensing, multiple-user spectrum sensing can overcome the impacts caused by the fading environment of cognitive radio. Since diversity technology has been proved to provide the system high transmission rate and high link reliability, we propose a diversity-based multi-antenna cooperative detection model based on the original cooperative detecting model. By introducing the antenna technology, sensing users are equipped with a multi-antenna system. Simulations show that the performance of our proposal is better than that of detection based on single-antenna in cognitive radio network. What's more, performance of cooperative detection based on multi-antenna is even better than that of cooperative detection based on single-antenna cognitive radio network.10aCooperative detection10aDiversity technique10aMulti-antenna technology10aSpectrum sensing1 aZhenquan, Q.1 aWenjing, L.1 aHuizhen, J.1 aWeifeng, S.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-84880787172&partnerID=40&md5=c40e6173f1ef81d864ae8908b3329067
