Exact Second-Order Asymptotics for Covert Communication over DMCs with Variational Distance Constraints
Qiaosheng Zhang, Lin Zhou, Xuelong Li
We determine the exact second-order asymptotics of covert communication over binary-input discrete memoryless channels when covertness is measured by variational distance. Previous…
Exponentially Consistent Low Complexity Tests for Statistical Sequence Matching
Lin Zhou
Towards practical applications of statistical sequence matching, we propose low complexity tests that are exponentially consistent and bound the exponential decay rates for error p…
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…
Resolution Limits of Non-Adaptive 20 Questions Estimation for Tracking Multiple Moving Targets
Chunsong Sun, Lin Zhou, Jingjing Wang +3
Motivated by the practical application of beam tracking of multiple devices in Multiple Input Multiple Output (MIMO) communication, we study the problem of non-adaptive twenty ques…
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…
