具有统计QoS约束的衰落信道安全广播

Secure Broadcasting over Fading Channels with Statistical QoS Constraints

Deli Qiao, Mustafa Cenk Gursoy, Senem Velipasalar

摘要:

在本文中,衰落广播信道与机密消息的研究中存在的统计服务质量(QoS)的限制,在缓冲区长度的形式。我们采用有效容量公式来衡量的机密和共同的消息的吞吐量。我们假设信道侧信息(CSI)在发射机和接收机处都是可用的。假设在发送端的平均功率约束,我们首先定义了有效的安全吞吐量区域,并证明了吞吐量区域是凸的。然后,我们得到的最佳功率控制策略,实现有效的安全吞吐量区域的边界点。

英文摘要:

In this paper, the fading broadcast channel with confidential messages is studied in the presence of statistical quality of service (QoS) constraints in the form of limitations on the buffer length. We employ the effective capacity formulation to measure the throughput of the confidential and common messages. We assume that the channel side information (CSI) is available at both the transmitter and the receivers. Assuming average power constraints at the transmitter side, we first define the effective secure throughput region, and prove that the throughput region is convex. Then, we obtain the optimal power control policies that achieve the boundary points of the effective secure throughput region.
