Low-Resolution ADC Quantized Full-Duplex Massive MIMO-Enabled Wireless Backhaul in Heterogeneous Networks Over Rician Channels
Prince Anokye, Roger Kwao Ahiadormey, Han-Shin Jo +2
This paper studies the spectral/energy efficiency (SE/EE) of a heterogeneous network with the backhaul enabled by low-resolution analog-to-digital converters (ADCs) quantized full-…
Beamforming and Resource Allocation for Multi-User Full-Duplex Wireless Powered Communications in IoT Networks
Derek Kwaku Pobi Asiedu, Sumaila Mahama, Changick Song +2
For a self-sustaining wireless communication system in Internet-of-Things (IoT) networks, energy harvesting (EH) can be implemented at each user node as a constant renewable power…
Leakage Rate Analysis for Artificial Noise Assisted Massive MIMO with Non-coherent Passive Eavesdropper in Block-fading
Changick Song
Massive MIMO is one of the salient techniques for achieving high spectral efficiency in next generation wireless networks. Recently, a combined strategy of the massive MIMO and the…
Optimal Precoder Designs for Sum-utility Maximization in SWIPT-enabled Multi-user MIMO Cognitive Radio Networks
Changick Song, Hoon Lee, Kyoung-Jae Lee
In this paper, we propose a generalized framework that combines the cognitive radio (CR) techniques for spectrum sharing and the simultaneous wireless information and power transfe…
MIMO Broadcasting for Simultaneous Wireless Information and Power Transfer: Weighted MMSE Approaches
Changick Song, Cong Ling, Jaehyun Park +1
We consider simultaneous wireless information and power transfer (SWIPT) in MIMO Broadcast networks where one energy harvesting (EH) user and one information decoding (ID) user sha…
Diversity of Linear Transceivers in MIMO AF Half-duplex Relaying Channels
Changick Song, Cong Ling
Linear transceiving schemes between the relay and the destination have recently attracted much interest in MIMO amplify-and-forward (AF) relaying systems due to low implementation…
Achievable Diversity-Rate Tradeoff of MIMO AF Relaying Systems with MMSE Transceivers
Changick Song, Cong Ling
This paper investigates the diversity order of the minimum mean squared error (MMSE) based optimal transceivers in multiple-input multiple-output (MIMO) amplify-and-forward (AF) re…
