Capacity of multi-channel cognitive radio systems: bits through channel selections
EURASIP Journal on Wireless Communications and Networking, 2018 The channel capacity of multi-channel cognitive radio systems is studied with the assumption of limited sensing capability. The randomness of sub-channel selection is utilized to convey information. Two types of sub-channels, memoryless and finite state,

Study of Combination Communication Regime
IEEE Access, 2022 In this paper, to the best of our knowledge, we propose a comprehensive combination communication regime for the first time, which uses the spatial position combination of different physical entities, rather than the change of physical parameters, to ...

On the capacity of the noncausal relay channel [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 This paper studies the noncausal relay channel, also known as the relay channel with unlimited lookahead, introduced by El Gamal, Hassanpour, and Mammen. Unlike the standard relay channel model, where the relay encodes its signal based on the previous received output symbols, the relay in the noncausal relay channel encodes its signal as a function of ...

Chain-Rules for Channel Capacity [PDF]
2021 IEEE International Symposium on Information Theory (ISIT), 2021 We show some chain-rules for the capacity of classical-quantum and quantum channels. We use the concept of Nash-Equilibrium in game-theory, and its existence in suitably defined games, to arrive at the chain-rules.

Strong converse for the quantum capacity of the erasure channel for almost all codes [PDF]
, 2014 A strong converse theorem for channel capacity establishes that the error probability in any communication scheme for a given channel necessarily tends to one if the rate of communication exceeds the channel's capacity.

On the capacity of MIMO interference channels [PDF]
2008 46th Annual Allerton Conference on Communication, Control, and Computing, 2008 The capacity region of a multiple-input-multiple-output interference channel (MIMO IC) where the channel matrices are square and invertible is studied. The capacity region for strong interference is established where the definition of strong interference parallels that of scalar channels.

An Upper Bound on the Capacity of non-Binary Deletion Channels [PDF]
, 2013 We derive an upper bound on the capacity of non-binary deletion channels. Although binary deletion channels have received significant attention over the years, and many upper and lower bounds on their capacity have been derived, such studies for the non ...

Mutual Information and Information Gating in Synfire Chains
Entropy, 2018 Coherent neuronal activity is believed to underlie the transfer and processing of information in the brain. Coherent activity in the form of synchronous firing and oscillations has been measured in many brain regions and has been correlated with enhanced
