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…

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…

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…
