On the Distribution of the Ratio of Products of Fisher-Snedecor Random Variables and Its Applications
Hongyang Du, Jiayi Zhang, Kostas P. Peppas +3
The Fisher-Snedecor distribution has been recently proposed as a more accurate and mathematically tractable composite fading model than traditional established models…
Distribution of the Sum of Fisher-Snedecor Random Variables and Its Applications
Hongyang Du, Jiayi Zhang, Julian Cheng +1
The statistical characterization of the sum of random variables (RVs) are useful for investigating the performance of wireless communication systems. We derive exact closed-form ex…
Prospective Multiple Antenna Technologies for Beyond 5G
Jiayi Zhang, Emil Björnson, Michail Matthaiou +3
Multiple antenna technologies have attracted large research interest for several decades and have gradually made their way into mainstream communication systems. Two main benefits…
Secure mmWave Communications in Cognitive Radio Networks
Hui Zhao, Jiayi Zhang, Liang Yang +2
In this letter, the secrecy performance in cognitive radio networks (CRNs) over fluctuating two-ray (FTR) channels, which is used to model the millimetre wave channel, is investiga…
Performance of Cell-Free Massive MIMO with Rician Fading and Phase Shifts
Özgecan Özdogan, Emil Björnson, Jiayi Zhang
In this paper, we study the uplink (UL) and downlink (DL) spectral efficiency (SE) of a cell-free massive multiple-input-multiple-output (MIMO) system with Rician fading channels.…
Coalition Game based Full-duplex Concurrent Scheduling in Millimeter Wave Wireless Backhaul Network
Haiyan Jiang, Yong Niu, Jiayi Zhang +2
With the development of self-interference (SI) cancelation technology, full-duplex (FD) communication becomes possible. FD communication can theoretically double the spectral effic…
