Energy Efficiency of Massive Random Access in MIMO Quasi-Static Rayleigh Fading Channels with Finite Blocklength
Junyuan Gao, Yongpeng Wu, Shuo Shao +2
This paper considers the massive random access problem in MIMO quasi-static Rayleigh fading channels. Specifically, we derive achievability and converse bounds on the minimum energ…
Massive Access for Future Wireless Communication Systems
Yongpeng Wu, Xiqi Gao, Shidong Zhou +3
Multiple access technology played an important role in wireless communication in the last decades: it increases the capacity of the channel and allows different users to access the…
On the Fundamental Limits of MIMO Massive Multiple Access Channels
Fan Wei, Yongpeng Wu, Wen Chen +2
In this paper, we study the multiple-antenna wireless communication networks, where a large number of devices simultaneously communicate with an access point. The capacity region o…
Wiretap Channels: Nonasymptotic Fundamental Limits
Wei Yang, Rafael F. Schaefer, H. Vincent Poor
This paper investigates the maximal secret communication rate over a wiretap channel subject to reliability and secrecy constraints at a given blocklength. New achievability and co…
Common-Message Broadcast Channels with Feedback in the Nonasymptotic Regime: Full Feedback
Kasper Fløe Trillingsgaard, Wei Yang, Giuseppe Durisi +1
We investigate the maximum coding rate achievable on a two-user broadcast channel for the case where a common message is transmitted with feedback using either fixed-blocklength co…
Beta-Beta Bounds: Finite-Blocklength Analog of the Golden Formula
Wei Yang, Austin Collins, Giuseppe Durisi +2
It is well known that the mutual information between two random variables can be expressed as the difference of two relative entropies that depend on an auxiliary distribution, a r…
