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.

Fading Broadcast Channels With State Information at the Receivers [PDF]
IEEE Transactions on Information Theory, 2012 Despite considerable progress on the information-theoretic broadcast channel, the capacity region of fading broadcast channels with channel state known at the receivers but unknown at the transmitter remains unresolved. We address this subject by introducing a layered erasure broadcast channel model in which each component channel has a state that ...

On the Gaussian MIMO Relay Channel With Full Channel State Information [PDF]
IEEE Transactions on Signal Processing, 2009 This paper addresses the problem of source and relay transmit covariance optimization on the Gaussian MIMO relay channel with full channel state information (CSI), i.e., assuming perfect knowledge of all channels. For full-duplex relaying, we show that the cut-set bound on capacity can be computed as the solution of a convex problem, thus providing a ...

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 ...

Smartphone-Based Indoor Fingerprinting Localization Using Channel State Information
IEEE Access, 2019 Indoor localization technology plays an important role in many indoor application scenarios. Existing WiFi-based indoor localization methods mainly obtain channel state information (CSI) through the personal computer, or obtain coarse-grained received ...

The Broadcast Approach in Communication Networks
Entropy, 2021 In this paper we review the theoretical and practical principles of the broadcast approach to communication over state-dependent channels and networks in which the transmitters have access to only the probabilistic description of the time-varying states ...

Channel Charting: Locating Users Within the Radio Environment Using Channel State Information
IEEE Access, 2018 We propose channel charting (CC), a novel framework in which a multi-antenna network element learns a chart of the radio geometry in its surrounding area.
