随着LTE?A系统中新技术的引入，PDCCH的容量和同频干扰逐渐成为制约系统性能的瓶颈。3GPP在Release 11中引入了E?PDCCH，对于E?PDCCH，这里详细研究其发送端的资源映射设计和接收端的盲检测算法，并在Matlab平台上对PDCCH和E?PDCCH的性能进行仿真比较。结果表明，在相同的配置条件下，E?PDCCH相对于PDCCH具有更低的误码率，更好的抗衰落性能。

With the introduction of new technologies in LTE?A system,the capacity and same frequency interference of PDCCH has become the bottleneck of system performance. E?PDCCH is introduced into 3GPP in Release 11. The design of re?source mapping in the transmitter and the blind detection algorithm in the receiver are studied in detail in this paper,and then the performances of PDCCH and EPDCCH were compared by simulation on downlink platform of Matlab. The results show that E?PDCCH has lower error rate and better anti?fading performance than PDCCH with the same configuration.
