Structured Matching Pursuit for Reconstruction of Dynamic Sparse Channels
Xudong Zhu, Linglong Dai, Guan Gui +3
In this paper, by exploiting the special features of temporal correlations of dynamic sparse channels that path delays change slowly over time but path gains evolve faster, we prop…
Tracking A Dynamic Sparse Channel Via Differential Orthogonal Matching Pursuit
Xudong Zhu, Linglong Dai, Wei Dai +2
This paper considers the problem of tracking a dynamic sparse channel in a broadband wireless communication system. A probabilistic signal model is firstly proposed to describe the…
Compressive sensing based differential channel feedback for massive MIMO
Wenqian Shen, Linglong Dai, Yi Shi +2
Massive multiple-input multiple-output (MIMO) is becoming a key technology for future 5G wireless communications. Channel feedback for massive MIMO is challenging due to the substa…
Soft Pilot Reuse and Multi-Cell Block Diagonalization Precoding for Massive MIMO Systems
Xudong Zhu, Zhaocheng Wang, Chen Qian +4
The users at cell edge of a massive multiple-input multiple-output (MIMO) system suffer from severe pilot contamination, which leads to poor quality of service (QoS). In order to e…
Smart Pilot Assignment for Massive MIMO
Xudong Zhu, Zhaocheng Wang, Linglong Dai +1
A massive multiple-input multiple-output (MIMO) system, which utilizes a large number of antennas at the base station (BS) to serve multiple users, suffers from pilot contamination…
Graph Coloring Based Pilot Allocation to Mitigate Pilot Contamination for Multi-Cell Massive MIMO Systems
Xudong Zhu, Linglong Dai, Zhaocheng Wang
A massive multiple-input multiple-output (MIMO) system, which utilizes a large number of base station (BS) antennas to serve a set of users, suffers from pilot contamination due to…
