Adaptive CSI Feedback with Hidden Semantic Information Transfer

Jiaqi Cao, Lixiang Lian, Yijie Mao, Bruno Clerckx

ICASSP 2023accepted

Channel state information (CSI) feedback has been a challenging task for downlink frequency division duplex (FDD) system. Meanwhile, sensory data collection in large-scale network is pivotal to support intelligent applications in the central server. In this paper, we propose a deep-learning-empowere…

Regularized Deep Generative Model Learning for Real-Time Massive MIMO Channel Tracking

Lixiang Lian, Ben Wang

ICASSP 2023accepted

Conventional deep neural network (DNN)-based channel estimator is trained offline and deployed online with fixed weights, lacking the adaptivity and generality to fast varying channels. In this paper, we propose a real-time compressive channel tracking (CT) algorithm based on regularized deep genera…
