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 ...

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

Non-contact Human Motion Recognition Method Based on Channel State Information [PDF]
Jisuanji gongcheng, 2021 The performance of traditional sensors and cameras in motion recognition are affected by the environmental factors and limited by the risk of violating user privacy.Taking the Peking Opera actions as the research object, this paper proposes a non-contact

Degrees of Freedom of Time Correlated MISO Broadcast Channel with Delayed CSIT
, 2012 We consider the time correlated multiple-input single-output (MISO) broadcast channel where the transmitter has imperfect knowledge on the current channel state, in addition to delayed channel state information. By representing the quality of the current

Two-User Erasure Interference Channels with Local Delayed CSIT
, 2016 We study the capacity region of two-user erasure interference channels with local delayed channel state information at the transmitters. In our model, transmitters have local mismatched outdated knowledge of the channel gains.

Degraded Broadcast Diamond Channels with Non-Causal State Information at the Source
, 2012 A state-dependent degraded broadcast diamond channel is studied where the source-to-relays cut is modeled with two noiseless, finite-capacity digital links with a degraded broadcasting structure, while the relays-to-destination cut is a general multiple ...
