Turbo Compressed Sensing with Partial DFT Sensing Matrix
Junjie Ma, Xiaojun Yuan, Li Ping
In this letter, we propose a turbo compressed sensing algorithm with partial discrete Fourier transform (DFT) sensing matrices. Interestingly, the state evolution of the proposed a…
Spectral Efficiency of the Cellular Two-Way Relaying with Large Antenna Arrays
Z. Fang, X. Wang, X. Yuan
This paper considers a multiuser cellular two-way relay network (cTWRN) where multiple users exchange information with a base station (BS) via a relay station (RS). Each user is eq…
Dynamic Nested Clustering for Parallel PHY-Layer Processing in Cloud-RANs
Congmin Fan, Ying Jun Zhang, Xiaojun Yuan
Featured by centralized processing and cloud based infrastructure, Cloud Radio Access Network (C-RAN) is a promising solution to achieve an unprecedented system capacity in future…
MIMO Multiway Relaying with Clustered Full Data Exchange: Signal Space Alignment and Degrees of Freedom
Xiaojun Yuan
We investigate achievable degrees of freedom (DoF) for a multiple-input multiple-output (MIMO) multiway relay channel (mRC) with clusters and users per cluster. Each user i…
Towards the Asymptotic Sum Capacity of the MIMO Cellular Two-Way Relay Channel
Zhaoxi Fang, Xiaojun Yuan, Xin Wang
In this paper, we consider the transceiver and relay design for multiple-input multiple-output (MIMO) cellular two-way relay channel (cTWRC), where a multi-antenna base station (BS…
MIMO Multiway Relaying with Pairwise Data Exchange: A Degrees of Freedom Perspective
Rui Wang, Xiaojun Yuan
In this paper, we study achievable degrees of freedom (DoF) of a multiple-input multiple-output (MIMO) multiway relay channel (mRC) where users, each equipped with antennas…
