Holographic interference filters for infrared communications [PDF]

open access: yesApplied Optics, 2003
We demonstrate that high-quality interference filters for the wavelength range 1300-1600 nm can be holographically fabricated in DuPont HRF-800X001 photopolymer material by use of visible laser illumination. We also summarize a chain-matrix technique, which we call thin-film decomposition, that is useful for modeling multilayer films with an arbitrary ...

Electromagnetic Interference in RIS-Aided Communications [PDF]

open access: yesIEEE Wireless Communications Letters, 2022
The prospects of using a reconfigurable intelligent surface (RIS) to aid wireless communication systems have recently received much attention. Among the different use cases, the most popular one is where each element of the RIS scatters the incoming signal with a controllable phase-shift, without increasing its power.

Exact BER of Rectangular-Constellation QAM Subjected to Asynchronous Co-Channel Interference and Nakagami-m Fading [PDF]

open access: yes, 2006
The exact average bit error ratio (BER) of the rectangular quadrature amplitude modulation (QAM) constellation is studied in the context of asynchronous co-channel interference (CCI) and Nakagami-m fading.

Interference Aspects of Adaptive Modems over Slow Rayleigh Fading Channels

open access: yes, 1999
Adaptive modulation can achieve channel capacity gains by adapting the number of bits per transmission symbol on a burst-by-burst basis, in harmony with channel quality fluctuations. This is demonstrated in the paper for target bit error rates of 1 and 0.

Overview of Interference Situation and Mitigation Techniques for LDACS1 [PDF]

open access: yes, 2011
LDACS1 is the broadband candidate technology for the future L-band digital aeronautical communications system. As unused spectrum is very scarce in the L-band, LDACS1 pursues the approach to make use of the gaps between adjacent channels used by the ...

An assessment of interference cancellation applied to BWA [PDF]

open access: yes, 2007
It is a general principle that a communication system should be designed to avoid interference in the first place, either through network planning or with effective radio resource management and medium access control.
