On the Ergodic Mutual Information of Keyhole MIMO Channels With Finite-Alphabet Inputs
Chongjun Ouyang, Ali Bereyhi, Saba Asaad +3
This letter studies the ergodic mutual information (EMI) of keyhole multiple-input multiple-output channels having finite-alphabet input signals. The EMI is first investigated for…
Asymptotic Average Mutual Information Over Finite Input Mixture Gamma Distributed Channels
Chongjun Ouyang, Sheng Wu, Chunxiao Jiang +3
This letter establishes a unified analytical framework to study the asymptotic average mutual information (AMI) of mixture gamma (MG) distributed fading channels driven by finite i…
MMSE Bound for MIMO Channel
Chongjun Ouyang, Hongwen Yang
Detailed derivations of two bounds of the minimum mean-square error (MMSE) of complex-valued multiple-input multiple-output (MIMO) systems are proposed for performance evaluation.…
On the Ergodic Capacity of Reconfigurable Intelligent Surface (RIS)-Aided MIMO Channels
Chongjun Ouyang, Hao Xu, Xujie Zang +1
Reconfigurable intelligent surfaces (RISs) have emerged as a promising technique to enhance the system spectral efficiency. This paper investigates the ergodic channel capacity (EC…
