Learning to Estimate: A Real-Time Online Learning Framework for MIMO-OFDM Channel Estimation

no code implementations22 May 2023 Lianjun Li, Sai Sree Rayala, Jiarui Xu, Lizhong Zheng, Lingjia Liu

In this paper we introduce StructNet-CE, a novel real-time online learning framework for MIMO-OFDM channel estimation, which only utilizes over-the-air (OTA) pilot symbols for online training and converges within one OFDM subframe.

Detect to Learn: Structure Learning with Attention and Decision Feedback for MIMO-OFDM Receive Processing

no code implementations17 Aug 2022 Jiarui Xu, Lianjun Li, Lizhong Zheng, Lingjia Liu

The DF mechanism further enhances detection performance by dynamically tracking the channel changes through detected data symbols.

RC-Struct: A Structure-based Neural Network Approach for MIMO-OFDM Detection

no code implementations3 Oct 2021 Jiarui Xu, Zhou Zhou, Lianjun Li, Lizhong Zheng, Lingjia Liu

The binary classifier enables the efficient utilization of the precious online training symbols and allows an easy extension to high-order modulations without a substantial increase in complexity.

Federated Learning in Mobile Edge Computing: An Edge-Learning Perspective for Beyond 5G

no code implementations15 Jul 2020 Shashank Jere, Qiang Fan, Bodong Shang, Lianjun Li, Lingjia Liu

Thus, in this paper, we design a novel edge computing-assisted federated learning framework, in which the communication constraints between IoT devices and edge servers and the effect of various IoT devices on the training accuracy are taken into account.
