合作频谱感知和适应环境，认知无线电能够填补频谱漏洞和服务，而不造成对授权用户的有害干扰。我们考虑优化的合作频谱感知与能量检测，以尽量减少总的错误率(Cooperative spectrum sensing and adaptive environment, cognitive radio can fill in spectrum loopholes and services without causing harmful interference to authorized users. We consider the optimization of cooperative spectrum sensing and energy detection to minimize the total error rate.)
