New Results on the Fluctuating Two-Ray Model with Arbitrary Fading Parameters and Its Applications
Jiayi Zhang, Wen Zeng, Xu Li +2
The fluctuating two-ray (FTR) fading model provides a much better fit than other fading models for small-scale fading measurements in millimeter wave communications. In this paper,…
Spectral and Energy Efficiency of Cell-Free Massive MIMO Systems with Hardware Impairments
Jiayi Zhang, Yinghua Wei, Emil Björnson +2
Cell-free massive multiple-input multiple-output (MIMO), with a large number of distributed access points (APs) that jointly serve the user equipments (UEs), is a promising network…
Spectral Efficiency of Multipair Massive MIMO Two-Way Relaying with Hardware Impairments
Jiayi Zhang, Xipeng Xue, Emil Björnson +2
We consider a multipair massive multiple-input multiple-output (MIMO) two-way relaying system, where multiple pairs of single-antenna devices exchange data with the help of a relay…
Multipair Massive MIMO Two-Way Full-Duplex Relay Systems with Hardware Impairments
Ying Liu, Xipeng Xue, Jiayi Zhang +3
Hardware impairments, such as phase noise, quantization errors, non-linearities, and noise amplification, have baneful effects on wireless communications. In this paper, we investi…
On the Performance of NOMA-Based Cooperative Relaying Systems over Rician Fading Channels
Ruicheng Jiao, Linglong Dai, Jiayi Zhang +2
Non-orthogonal multiple access (NOMA) is a promising technique for the fifth generation (5G) wireless communications. As users with good channel conditions can serve as relays to e…
Novel Device-to-Device Discovery Scheme based on Random Backoff in LTE-Advanced Networks
Jiayi Zhang, Likai Deng, Xu Li +3
Device-to-Device (D2D) discovery is a key enabler of D2D communications for the direct exchange of local area traffic between proximity users (UEs) to improve spectral efficiency.…
