Joint Optimization of Tile Allocation and Beam Centering in Shared IRS for Multi-Link FSO Systems

Free space optical (FSO) systems due to their large bandwidth, secure and cost-efficient data transmission are considered as suitable candidates for next generation wireless communication networks and beyond. However, the limiting factor in such systems is the requirement of a line-of-sight (LOS) li...

Molecular Communication in Ducts in the Presence of Gravity

Recently, the application of communication engineering principles to biomedical problems has spawned the emerging interdisciplinary research field of molecular communication (MC). MC is ubiquitous in natural biological systems and has a high potential for bio-medical applications such as tar...

Performance of SWIPT Systems Employing Practical TX Pulse Shaping Filters and Nonlinear EH Circuits with Memory

Simultaneous Wireless Information and Power Transfer (SWIPT) is a promising technology that enables wireless recharging of device batteries along with information transmission. A SWIPT system usually comprises a transmitter (TX) that sends a common signal to an information receiver and an energy har...

Rate-Power Regions of Adaptive SWIPT Systems with Energy Harvester State Information Feedback

Simultaneous Wireless Information and Power Transfer (SWIPT) is a promising technology that enables wireless recharging of device batteries along with information transmission. SWIPT systems usually assume a transmitter (TX) that sends a common signal to an information receiver (IR) and an energy ha...

Matrix Factorization in MIMO Systems and Machine Learning

Many applications of digital signal processing rely on multiplications of a stream of unknown vectors with a single fixed matrix. Examples of such applications include MIMO precoding in a wireless communication system, signal detection, and machine learning using, e.g., an artificial neural network....

The Role of Molecule Spillover in Multi-Synapse Molecular Communication

The design of communication networks for nanodevices, so-called nanonetworks, has gained a lot of attention. Nanonetworks could enable exciting new applications in biomedicine, environmental monitoring, and manufacturing. Molecular communication (MC), i.e., the exchange of information via molecules, is a bio-hybrid approach to nanonetwork design.
