Abstract: Inter-symbol interference (ISI) causes many errors in modulated symbols, when they are transmitted through band-limited channels. According to the multipath delay profile of the channel, the modulated symbol may disperse over more than one symbol… read more here.

DOI: 10.1109/lcomm.2024.3502152
Abstract: The high Doppler effect and severe multipath delay are among the major challenges in air-to-ground (A2G) communication scenarios, where the maximum multipath delay may exceed the duration of one or more orthogonal frequency division multiplexing… read more here.

DOI: 10.1109/tcsi.2016.2601026
Abstract: Dynamic element matching (DEM) is often applied to multi-bit DACs to avoid nonlinear distortion that would otherwise result from inevitable mismatches among nominally identical circuit elements. Unfortunately, for such a DEM DAC to fully achieve… read more here.

DOI: 10.1364/oe.26.003260
Abstract: One primary challenge in wireless ultraviolet communications (UVCs) is the inter-symbol-interference (ISI), which may block the detection of current informative signal, especially when channel-related characteristics are unknown. In this paper, we propose a UV channel-related… read more here.

DOI: 10.1364/oe.553542
Abstract: Scattering-based ultraviolet (UV) transmission is a crucial method for realizing non-line-of-sight (NLOS) optical communications. However, the inherent multipath characteristics of scattering channels can induce inter-symbol interference (ISI), significantly limiting signal transmission efficiency. To mitigate the… read more here.
