Functional forwarding of channel state information
2009 IEEE International Symposium on Information Theory, 2009 In large relay networks, the assumption of full and perfect channel knowledge at the destination is optimistic in practice. The fading coefficients are typically measured at the relays but not directly known at the destination. Traditionally, each fading coefficient is individually forwarded to the destination.

Wiretap Channel with Action-Dependent Channel State Information [PDF]
Entropy, 2013 In this paper, we investigate the model of wiretap channel with action-dependent channel state information. Given the message to be communicated, the transmitter chooses an action sequence that affects the formation of the channel states, and then ...

Decimeter Ranging With Channel State Information [PDF]
IEEE Transactions on Wireless Communications, 2019 This paper aims at the problem of time-of-flight (ToF) estimation using channel state information (CSI) obtainable from commercialized MIMO-OFDM WLAN receivers. It was often claimed that the CSI phase is contaminated with errors of known and unknown natures rendering ToF-based positioning difficult. To search for an answer, we take a bottom-up approach

Road State Inference via Channel State Information
IEEE Transactions on Vehicular Technology, 2023 A wide variety of sensor technologies are recently being adopted for traffic monitoring applications. Since most of these technologies rely on wired infrastructure, the installation and maintenance costs limit the deployment of the traffic monitoring systems. In this paper, we introduce a traffic monitoring approach that exploits physical layer samples

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 ...

Deep Learning-Based Fall Detection Using WiFi Channel State Information
IEEE Access, 2023 Falls have always been one of the major threats to the health and well-being of elderly people, particularly for those living alone. Both wearable and non-wearable fall detection systems have already been developed.

Impact of Imperfect Channel State Information on RS Coding Aided Hybrid-ARQ in Rayleigh Fading Channels [PDF]
, 2010 Hybrid Automatic-Repeat-reQuest (ARQ) schemes are capable of maintaining reliable communications for transmission over hostile wireless channels. In coherent detection aided schemes, the achievable performance substantially depends on the accuracy of ...
