Scalable Uplink Signal Detection in C-RANs via Randomized Gaussian Message Passing
Congmin Fan, Xiaojun Yuan, Ying Jun Zhang
Cloud Radio Access Network (C-RAN) is a promising architecture for unprecedented capacity enhancement in next-generation wireless networks thanks to the centralization and virtuali…
Fundamental Limits of Training-Based Multiuser MIMO Systems
Xiaojun Yuan, Congmin Fan, Ying Jun Zhang
In this paper, we endeavour to seek a fundamental understanding of the potentials and limitations of training-based multiuser multiple-input multiple-output (MIMO) systems. In a mu…
On the Degrees of Freedom of the Symmetric Multi-Relay MIMO Y Channel
Tian Ding, Xiaojun Yuan, Soung Chang Liew
In this paper, we study the degrees of freedom (DoF) of the symmetric multi-relay multiple-input multiple-output (MIMO) Y channel, where three user nodes, each with M antennas, com…
Compute-Compress-and-Forward: Exploiting Asymmetry of Wireless Relay Networks
Yihua Tan, Xiaojun Yuan
Compute-and-forward (CF) harnesses interference in a wireless networkby allowing relays to compute combinations of source messages. The computed message combinations at relays are…
On the Performance of Turbo Signal Recovery with Partial DFT Sensing Matrices
Junjie Ma, Xiaojun Yuan, Li Ping
This letter is on the performance of the turbo signal recovery (TSR) algorithm for partial discrete Fourier transform (DFT) matrices based compressed sensing. Based on state evolut…
