Model-Driven Channel Estimation for OFDM Systems Based on Image Super-Resolution Network
Xin Ru, Li Wei, Youyun Xu
In this paper, we propose a model-driven channel estimation method utilizing a convolutional neural network (CNN) derived from image super-resolution (SR). Instead of completely ab…
Closed-form, robust and accurate multi-frequency phase unwrapping: frequency design and algorithm
Li Wei, Wangdong Qi
A closed-form algorithm, named "concerto", is proposed for phase-based distance estimation in multi-frequency phase unwrapping (MFPU) system. The concerto method consists of three…
Hardware Impairments Aware Transceiver for Full-Duplex Massive MIMO Relaying
Xiaochen Xia, Dongmei Zhang, Kui Xu +2
This paper studies the massive MIMO full-duplex relaying (MM-FDR), where multiple source-destination pairs communicate simultaneously with the help of a common full-duplex relay eq…
Max-SINR Receiver for HMCT Systems over Non-Stationary Doubly Dispersive Channel
Kui Xu, Youyun Xu, Dongmei Zhang +1
In this paper, a maximizing Signal-to-Interference plus-Noise Ratio (Max-SINR) receiver for Hexagonal Multicarrier Transmission (HMCT) system over non-stationary doubly dispersive…
Performance Analysis of Interference-Limited Three-Phase Two-Way Relaying with Direct Channel
Xiaochen Xia, Dongmei Zhang, Kui Xu +1
This paper investigates the performance of interference-limited three-phase two-way relaying with direct channel between two terminals in Rayleigh fading channels. The outage proba…
Joint Physical Network Coding and LDPC decoding for Two Way Wireless Relaying
Kui Xu, Zhenxing Lv, Youyun Xu +3
In this paper, we investigate the joint design of channel and network coding in bi-directional relaying systems and propose a combined low complexity physical network coding and LD…
