论文摘要
在本文中，我们研究了两用户多输入多输出（MIMO）广播通道的安全速率分解，并在发射机（CSIT）和一个多重安德纳纳Jammer上使用不完美的通道状态信息，每个接收器都具有相等数量的天线，Jammer具有完美的通道信息（CSI）。具体而言，我们设计了一个安全的速率分拆多访问策略，在其中，通过使用关节nulling和对不同天线配置的关节删除和对齐泄漏信息来确保私有和通用消息的安全性。此外，我们表明，通过安全速率拆分实现的汇总度（SDOF）是最佳的，并且通过常规的零效率优于表现。因此，我们揭示了具有不完美的CSIT和干扰器的两用户MIMO广播频道的汇率，并在这种情况下以MIMO的重点验证了速率拆分对安全目的的优越性。
In this paper, we investigate the secure rate-splitting for the two-user multiple-input multiple-output (MIMO) broadcast channel with imperfect channel state information at the transmitter (CSIT) and a multiple-antenna jammer, where each receiver has an equal number of antennas and the jammer has perfect channel state information (CSI). Specifically, we design a secure rate-splitting multiple-access strategy, where the security of split private and common messages is ensured by precoder design with joint nulling and aligning the leakage information, regarding different antenna configurations. Moreover, we show that the sum-secure degrees-of-freedom (SDoF) achieved by secure rate-splitting is optimal and outperforms that by conventional zero-forcing. Therefore, we reveal the sum-SDoF of the two-user MIMO broadcast channel with imperfect CSIT and a jammer, and validate the superiority of rate-splitting for the security purpose in this scenario with emphasis of MIMO.
