Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Channel Coding for Power Line Communication Based on Oversampled Filter Banks

, 2005
Oversampled filter banks (OSFB) can be applied as channel coding and have shown benefits in correlated and impulsive noise. Therefore, in this paper, we consider such channel coders for a power line communications scenario, where such conditions create a

Subband Adaptive Equaliser Tracking for Fractionally-Sampled Fading Broadband MIMO Channels [PDF]

, 2005
This paper demonstrates the performance of a subband adaptive multiple-input multiple-output (MIMO) equaliser tracking the inverse of a Doppler-filtered Rayleigh-fading broadband channel. The subband adaptive equaliser is shown to outperform the fullband
