研究了具有保密信息的两用户MIMO高斯广播信道。对于发射机具有用于两个用户的一个公共消息和用于用户1的一个机密消息的情况，容量区域的特征在于对用户2完全保密的机密消息。对于发射机具有用于两个用户的一个公共消息、每个用于用户之一的两个私有消息以及每个也用于用户之一的两个机密消息的情况，经由确定性方法提供容量区域的近似表征，其中机密消息分别对另一用户保密。
The two-user MIMO Gaussian broadcast channel with confidential messages is studied. For the case in which the transmitter has one common message for both users and one confidential message for user 1, the capacity region is characterized with the confidential message perfectly secret from user 2. For the case in which the transmitter has one common message for both users, two private messages each for one of the users, and two confidential messages each also for one of the users, an approximate characterization of the capacity region was provided via a deterministic approach with the confidential messages respectively secret from the other user.
