A Universal Random Precoding Framework for MIMO Systems
Jiazhen Dong, Lei Liu, Xiaojun Yuan +1
Current wireless systems combat inter-symbol interference (ISI) by diagonalizing or sparsifying the channel matrix, yet they remain vulnerable to selective fading. To address this,…
Channel Estimation in Massive MIMO Systems with Orthogonal Delay-Doppler Division Multiplexing
Dezhi Wang, Chongwen Huang, Xiaojun Yuan +6
Orthogonal delay-Doppler division multiplexing~(ODDM) modulation has recently been regarded as a promising technology to provide reliable communications in high-mobility situations…
Exploring Channel Estimation and Signal Detection for ODDM-based ISAC Systems
Dezhi Wang, Chongwen Huang, Lei Liu +5
Inspired by providing reliable communications for high-mobility scenarios, in this letter, we investigate the channel estimation and signal detection in integrated sensing and comm…
Channel Mapping Based on Interleaved Learning with Complex-Domain MLP-Mixer
Zirui Chen, Zhaoyang Zhang, Zhaohui Yang +1
In multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems, representing the whole channel only based on partial subchannels will significan…
