Machine learning based low-complexity channel state information estimation
EURASIP Journal on Advances in Signal Processing, 2023 In 5G communications, the acquisition of accurate channel state information (CSI) is of great importance to the hybrid beamforming of millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) system.

Cooperative Multiple-Access Channels With Distributed State Information [PDF]
IEEE Transactions on Information Theory, 2021 This paper studies a memoryless state-dependent multiple access channel (MAC) where two transmitters wish to convey a message to a receiver under the assumption of causal and imperfect channel state information at transmitters (CSIT) and imperfect channel state information at receiver (CSIR).

Uplink Assisted MIMO Channel Feedback Method Based on Deep Learning
Entropy, 2023 In order to solve the problem wherein too many base station antennas are deployed in a massive multiple-input–multiple-output system, resulting in high overhead for downlink channel state information feedback, this paper proposes an uplink-assisted ...

Wiretap Channel with Rate-Limited Channel State Information [PDF]
Mathematical Problems in Engineering, 2015 We revisit a channel coding problem where the channel state information (CSI) is rate-limited (or coded) and available to the channel encoder. A wiretapper is added into this model, and the confidential message is intended only for the legal receiver and should be kept from being eavesdropped by the wiretapper.

ParEst: joint estimation of the OFDM channel state information in MIMO systems
EURASIP Journal on Wireless Communications and Networking, 2020 OFDM channel state information (CSI) is needed for determining key parameters in MIMO transmissions. In this paper, a novel CSI estimation method, ParEst, is proposed, which estimates the CSI from multiple transmitting antennas simultaneously.

Behavior Recognition Method Based on Channel State Information in Through-the-Wall [PDF]
Jisuanji gongcheng, 2021 The passive behavior recognition method provided by Wi-Fi CSI has been applied in many scenarios, but the existing systems hardly consider the scene where the signal passes through the wall, or the sharp decline in recognition accuracy after the signal ...
