摘要：
In this paper, we study a wireless cooperative secure transmission system with the help of a friendly cooperative jammer Chad to interfere a potential malicious eavesdropper Eve. For imperfect channel estimation, we continue to follow the optimal power allocation and the maximum secrecy rate design of the perfect channel. Considering channel estimation scenario in the actual communication environment, we find that the small channel errors lead to a dramatic decrease in secure performance if the transmission design of the secure system is fixed.
