Physical Layer Service Integration in 5G: Potentials and Challenges
Weidong Mei, Zhi Chen, Jun Fang +1
High transmission rate and secure communication have been identified as the key targets that need to be effectively addressed by fifth generation (5G) wireless systems. In this con…
Quantization Design and Channel Estimation for Massive MIMO Systems with One-Bit ADCs
Feiyu Wang, Jun Fang, Hongbin Li +1
We consider the problem of channel estimation for uplink multiuser massive MIMO systems, where, in order to significantly reduce the hardware cost and power consumption, one-bit an…
When mmWave Communications Meet Network Densification: A Scalable Interference Coordination Perspective
Wei Feng, Yanmin Wang, Dengsheng Lin +3
The millimeter-wave (mmWave) communication is envisioned to provide orders of magnitude capacity improvement. However, it is challenging to realize a sufficient link margin due to…
Artificial Noise-Aided Biobjective Transmitter Optimization for Service Integration in Multi-User MIMO Gaussian Broadcast Channel
Weidong Mei, Zhi Chen, Jun Fang +1
This paper considers an artificial noise (AN)-aided transmit design for multi-user MIMO systems with integrated services. Specifically, two sorts of service messages are combined a…
Compressive Channel Estimation and Multi-user Detection in C-RAN
Qi He, Tony Q. S. Quek, Zhi Chen +1
This paper considers the channel estimation (CE) and multi-user detection (MUD) problems in cloud radio access network (C-RAN). Assuming that active users are sparse in the network…
