论文摘要
防空道通道估计（ANECE）是一种使用专门设计的飞行员信号的方法，可以允许使用一个或多个天线的两个或多个全双工无线电设备估算其通道状态信息（CSI）一致地，同时又可以防止Eavesdropper（EVE）和任何数量的天线一致地凝结了其CSI。本文根据两个标准介绍了AECE飞行员的最佳设计。第一个是用户的通道估计的平方误差（MSE），第二个是用户观察到的飞行员驱动信号之间的共同信息（MI）。封闭形式的最佳飞行员在符合对称和各向同性条件下的sum-mse和sum-MI标准下显示。用于计算最佳飞行员的算法显示了一般情况。讨论了三个或更多用户的公平问题。比较了不同设计的性能。
Anti-eavesdropping channel estimation (ANECE) is a method that uses specially designed pilot signals to allow two or more full-duplex radio devices each with one or more antennas to estimate their channel state information (CSI) consistently and at the same time prevent eavesdropper (Eve) with any number of antennas from obtaining its CSI consistently. This paper presents optimal designs of the pilots for ANECE based on two criteria. The first is the mean squared error (MSE) of channel estimation for the users, and the second is the mutual information (MI) between the pilot-driven signals observed by the users. Closed-form optimal pilots are shown under the sum-MSE and sum-MI criteria subject to a symmetric and isotropic condition. Algorithms for computing the optimal pilots are shown for general cases. Fairness issues for three or more users are discussed. The performances of different designs are compared.
