On Channels With Partial Channel State Information at the Transmitter
IEEE Transactions on Information Theory, 2005We consider an independent and identically distributed (i.i.d.) state-dependent channel with partial (rate-limited) channel state information (CSI) at the transmitter (CSIT) and full CSI at the receiver (CSIR). The CSIT comprises two parts, both subject to a rate constraint, and communicated over noiseless way-side channels. The first part is coded CSI,

Channels with state information and mismatched decoding
2016 IEEE Information Theory Workshop (ITW), 2016A single-user state-dependent channel with mismatched decoding is considered. Several setups are studied, which differ by the manner in which the state information is available to the encoder (causally or non-causally), and by whether or not the decoder is cognizant of the state sequence.

Cognitive interference channels with state information
2008 IEEE International Symposium on Information Theory, 2008Cognitive state-dependent interference channels are analyzed. We focus on the two-user case with two message sources. One of the transmitters, referred to as the cognitive informed user, knows both messages and also the states of the channel in a non-causal manner.

Information freshness over a Markov channel: The effect of channel state information
Ad Hoc Networks, 2019Abstract We consider a communication problem in which a source desires to maintain the freshness of the information updates it sends to a destination, over a channel that varies according to a Markov chain. Freshness is quantified in terms of the age metric (unlike the familiar delay metric), which refers to the difference between the current time ...

Multiple-Access Channels with Distributed Channel State Information
2007 IEEE International Symposium on Information Theory, 2007This paper considers a multiple-access channel with two state components, where the first sender knows only the first state component, the second sender knows only the second component, and the receiver knows both components. The notion of adaptive-rate capacity is introduced to characterize the set of achievable rates when the state is fixed in each ...

State-dependent channels with composite state information at the encoder
2011 IEEE Information Theory Workshop, 2011State-dependent channels have received much attention over the years, due to their relevance in many different network and multi-user communication scenarios. Nonetheless, previous treatments of this problem assumed that all of the state is available in the same manner: causally, non-causally or non-causally with a finite look-ahead.

Block fading channels with limited channel state information
2010 International Symposium On Information Theory & Its Applications, 2010In this paper, we provide a lower bound to maximum expected rate for block fading channels with limited Channel State Information (CSI). We assume a channel fading block accommodates at least one codeword so that for block Rayleigh fading, the ergodic channel capacity is zero when no CSI is available at the transmitter.

Understanding of Channel State Information
2021Channel State Information (CSI) is one of the major types of data used in wireless sensing, thanks to its fine subcarrier-level granularity and easy access with commodity Wi-Fi devices. While it is feasible to simply process CSI as numeric data, understanding the underlying model can guide the development of more effective wireless sensing algorithms ...

WiFi Sensing with Channel State Information
ACM Computing Surveys, 2019With the high demand for wireless data traffic, WiFi networks have experienced very rapid growth, because they provide high throughput and are easy to deploy. Recently, Channel State Information (CSI) measured by WiFi networks is widely used for different sensing purposes.

Broadcasting with channel state information
Processing Workshop Proceedings, 2004 Sensor Array and Multichannel Signal, 2005We consider the problem of transmit downlink beamforming for wireless transmission in the context of certain broadcasting or multicasting applications wherein channel state information (CSI) is available at the transmitter, and a common message is to be transmitted to the users. Unlike the usual "blind" isotropic broadcasting scenario, the availability
