摘　　要：信道估计在OFDM通信过程中发挥着重要作用。根据灵巧干扰的策略,文章提出了基于导频信道估计的灵巧干扰方法,在广义平稳非相关散射信道模型下进行了仿真,并和常规干扰方式进行了性能比较。仿真表明:基于导频信道估计的灵巧干扰方法是干扰OFDM信号的一种有效方法。Channel estimation plays a vital role in communication of OFDM. According jamming strategy, a smart jamming scheme based on pilot assisted channel estimation is to the smart its performance is simulated under the wide-sense stationary uncorrelated scattering（WSSUS） channel circumstance. Compared with the traditional jamming performance, it can be concluded that the smart jamming scheme based on pilot assisted channel estimation is an effective method to jam the OFDM signals.
