Measurements on the Efficiency of Overlapping Channels [PDF]

open access: yes2007 2nd IEEE Workshop on Networking Technologies for Software Define Radio Networks, 2007
We have investigated the radio interference behavior of a multi-channel WSN system with a typical radio platform. We have analyzed the results in terms of throughput and throughput per-channel spacing. The experimental results show that we can adjust the channel spacing with respect to the level of tolerated interference according to the application ...

Channels, measurements, and postselection in quantum thermodynamics [PDF]

open access: yesPhysical Review E, 2021
We analyse the benefit, in terms of extracting work, of having a single use of a quantum channel or measurement in quantum thermodynamics. This highlights a connection between unital and catalytic channels, and some subtleties concerning the conditional work cost of implementing a measurement given that a certain result was obtained.

Performance Comparison with Different Antenna Properties in Time Reversal Ultra-Wideband Communications for Sensor System Applications

open access: yesSensors, 2017
The complexity reduction of receivers in ultrawideband (UWB) communication when time reversal (TR) technique is applied makes it suitable for low-cost and low-power sensor systems.
