State Amplification [PDF]

open access: yes, 2008
We consider the problem of transmitting data at rate R over a state dependent channel p(y|x,s) with the state information available at the sender and at the same time conveying the information about the channel state itself to the receiver. The amount of

Behavior Recognition Method Based on Channel State Information in Through-the-Wall [PDF]

open access: yesJisuanji 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 ...

Capacity Region of Finite State Multiple-Access Channel with Delayed State Information at the Transmitters [PDF]

open access: yes, 2011
A single-letter characterization is provided for the capacity region of finite-state multiple access channels. The channel state is a Markov process, the transmitters have access to delayed state information, and channel state information is available at

Smartphone-Based Indoor Fingerprinting Localization Using Channel State Information

open access: yesIEEE 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 Benefit of Encoder Cooperation in the Presence of State Information [PDF]

open access: yes, 2017
In many communication networks, the availability of channel state information at various nodes provides an opportunity for network nodes to work together, or "cooperate." This work studies the benefit of cooperation in the multiple access channel with a ...

Interference management with mismatched partial channel state information

open access: yesEURASIP Journal on Wireless Communications and Networking, 2017
We study the fundamental limits of communications over multi-layer wireless networks where each node has only limited knowledge of the channel state information.

The Broadcast Approach in Communication Networks

open access: yesEntropy, 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 ...

On the Degrees of Freedom of time correlated MISO broadcast channel with delayed CSIT [PDF]

open access: yes, 2012
We consider the time correlated MISO broadcast channel where the transmitter has partial knowledge on the current channel state, in addition to delayed channel state information (CSI).

Fast compression of OFDM channel state information with constant frequency sinusoidal approximation

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
We propose CSIApx, a very fast and lightweight method to compress the channel state information (CSI) of Wi-Fi networks. CSIApx approximates the CSI vector as the linear combination of a small number of base sinusoids on constant frequencies and uses the
