Anti-eavesdropping channel estimation (ANECE) among two or more cooperative full-duplex radio devices allows these devices to obtain consistent estimates of their receive channel state information (CSI) with respect to each other but at the same time prevents eavesdropper (Eve) from obtaining a consistent estimate of its receive CSI, which improves the secrecy of subsequent transmission of information between the devices. This paper presents an analysis of secrecy throughput of ANECE assisted transmission of information between such single-antenna devices against Eve with multiple antennas. The analysis is based on finite blocklength coding and assumes that Eve applies a standard approach for information detection. Easy-to-compute analytical expressions of secrecy throughput in terms of various controllable parameters are obtained. Numerical results are presented and discussed.
