Intelligent Power Control for Spectrum Sharing in Cognitive Radios: A Deep Reinforcement Learning Approach
Xingjian Li, Jun Fang, Wen Cheng +3
We consider the problem of spectrum sharing in a cognitive radio system consisting of a primary user and a secondary user. The primary user and the secondary user work in a non-coo…
Channel Estimation for TDD/FDD Massive MIMO Systems with Channel Covariance Computing
Hongxiang Xie, Feifei Gao, Shi Jin +2
In this paper, we propose a new channel estimation scheme for TDD/FDD massive MIMO systems by reconstructing uplink/downlink channel covariance matrices (CCMs) with the aid of arra…
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…
Millimeter Wave Channel Estimation via Exploiting Joint Sparse and Low-Rank Structures
Xingjian Li, Jun Fang, Hongbin Li +1
We consider the problem of channel estimation for millimeter wave (mmWave) systems, where, to minimize the hardware complexity and power consumption, an analog transmit beamforming…
Super-resolution channel estimation for mmWave massive MIMO with hybrid precoding
Chen Hu, Linglong Dai, Talha Mir +2
Channel estimation is challenging for millimeter-wave (mmWave) massive MIMO with hybrid precoding, since the number of radio frequency (RF) chains is much smaller than that of ante…
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…
