Second-Order Asymptotics for Covert Communication over Quasi-Static Multiple-Antenna Fading Channels
Changhong Liu, Jingjing Wang, Qiaosheng Zhang +2
We study the second-order asymptotics of optimal codes for covert communication over quasi-static multi-antenna fading channels, under the covertness metric of Kullback--Leibler (K…

Exponentially Consistent Low Complexity Tests for Outlier Hypothesis Testing
Jun Diao, Jingjing Wang, Lin Zhou
We revisit outlier hypothesis testing, propose exponentially consistent low complexity fixed-length and sequential tests and show that our tests achieve better tradeoff between det…

Large Deviations for Sequential Tests of Statistical Sequence Matching
Lin Zhou, Qianyun Wang, Yun Wei +1
We revisit the problem of statistical sequence matching initiated by Unnikrishnan (TIT 2015) and derive theoretical performance guarantees for sequential tests that have bounded ex…
