Channel interference in multiphoton absorption [PDF]
The Journal of Chemical Physics, 2017 We extend the theory of channel interference to higher-order multiphoton absorption processes. We derive an explicit expression for channel interference in a three-photon absorption process and propose a general scheme for deriving such expressions for multiphoton absorption processes of any order.

On the Energy Efficiency of Interference Alignment in the
IEEE Access, 2019 Interference alignment (IA) is regarded as an important physical-layer interference management technique. Most research contributions on IA were focused on the analysis of its achievable spectral efficiency, either from the degrees of freedom or from the

ICBCA – Improved Cluster Based Channel Allocation in Cognitive Radio Sensor Networks
Journal of Telecommunications and Information Technology, 2020 Wireless sensor networks (WSNs) operate in an overcrowded electromagnetic environment, as the spectrum is shared by various wireless communication technologies. This gives rise to various challenges related to optimized and efficient spectrum utilization.

Retrospective Interference Alignment for the MIMO interference broadcast channel [PDF]
2015 IEEE International Symposium on Information Theory (ISIT), 2015 The degrees of freedom (DoF) of the multiple-input multiple-output (MIMO) Interference Broadcast Channel (IBC) with 2 cells and 2 users per cell are investigated when only delayed channel state information is available at the transmitter side (delayed CSIT).

Gaussian Interference Channel With Intermittent Feedback [PDF]
IEEE Transactions on Information Theory, 2015 We investigate how to exploit intermittent feedback for interference management by studying the two-user Gaussian interference channel (IC). We approximately characterize (within a universal constant) the capacity region for the Gaussian IC with intermittent feedback.

An Information-Spectrum Approach to the Capacity Region of the Interference Channel
Entropy, 2017 In this paper, a general formula for the capacity region of a general interference channel with two pairs of users is derived, which reveals that the capacity region is the union of a family of rectangles. In the region, each rectangle is determined by a

Deep Learning-Based Autoencoder for m-User Wireless Interference Channel Physical Layer Design
IEEE Access, 2020 Deep learning (DL) based autoencoder (AE) has been proposed recently as a promising, and potentially disruptive approach to design the physical layer of beyond-5G communication systems. Compared to a traditional communication system with a multiple-block

On channel output feedback in deterministic interference channels [PDF]
2009 IEEE Information Theory Workshop, 2009 In this paper, we study the effect of channel output feedback on the sum capacity in a two-user symmetric deterministic interference channel. We find that having a single feedback link from one of the receivers to its own transmitter results in the same sum capacity as having a total of 4 feedback links from both the receivers to both the transmitters.
