Trainable Joint Channel Estimation, Detection and Decoding for MIMO URLLC Systems

1 code implementation11 Apr 2024 Yi Sun, Hong Shen, Bingqing Li, Wei Xu, Pengcheng Zhu, Nan Hu, Chunming Zhao

The receiver design for multi-input multi-output (MIMO) ultra-reliable and low-latency communication (URLLC) systems can be a tough task due to the use of short channel codes and few pilot symbols.

Robust MIMO Detection With Imperfect CSI: A Neural Network Solution

no code implementations24 Jul 2023 Yi Sun, Hong Shen, Wei Xu, Nan Hu, Chunming Zhao

Furthermore, a robust detection network RADMMNet is constructed by unfolding the ADMM iterations and employing both model-driven and data-driven philosophies.

ICINet: ICI-Aware Neural Network Based Channel Estimation for Rapidly Time-Varying OFDM Systems

no code implementations18 Jun 2021 Yi Sun, Hong Shen, Zhenguo Du, Lan Peng, Chunming Zhao

A novel intercarrier interference (ICI)-aware orthogonal frequency division multiplexing (OFDM) channel estimation network ICINet is presented for rapidly time-varying channels.

Deep Learning Based Equalizer for MIMO-OFDM Systems with Insufficient Cyclic Prefix

no code implementations23 Jul 2020 Yan Sun, Chao Wang, Huan Cai, Chunming Zhao, Yiqun Wu, Yan Chen

In this paper, we study the equalization design for multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems with insufficient cyclic prefix (CP).

A Neural Network Aided Approach for LDPC Coded DCO-OFDM with Clipping Distortion

no code implementations4 Sep 2018 Yuan He, Ming Jiang, Chunming Zhao

In this paper, a neural network-aided bit-interleaved coded modulation (NN-BICM) receiver is designed to mitigate the nonlinear clipping distortion in the LDPC coded direct currentbiased optical orthogonal frequency division multiplexing (DCOOFDM) systems.
