Orthogonal Space Time Block Coding for Spatial Pulse Position Modulation
Guangtongxin yanjiu, 2021 The system performance of Spatial Pulse Position Modulation (SPPM) is poor in turbulent channels. In order to solve this problem, the bit complement orthogonal space time Block Coding for Spatial Pulse Position Modulation (BCOSTBCSPPM) is proposed by ...

Adaptive minimum bit-error-rate filtering
, 2004 Adaptive filtering has traditionally been developed based on the minimum mean square error (MMSE) principle and has found ever-increasing applications in communications. The paper develops adaptive filtering based on an alternative minimum bit error rate

Time Domain Equalizer Design Using Bit Error Rate Minimization for UWB Systems
EURASIP Journal on Wireless Communications and Networking, 2009 Ultra-wideband (UWB) communication systems occupy huge bandwidths with very low power spectral densities. This feature makes the UWB channels highly rich in resolvable multipaths.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Spectrally Efficient DMT Operation With BER-Informed Dynamic Bit and Power Loading
IEEE Access, 2022 This paper elucidates the relative benefits of bit loading and power loading for discrete multitone (DMT) modulation over wireline links. There is considerable variability in the use of bit and power loading in recent research on DMT for wireline ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Journal of Marine Science and Engineering, 2021 Turbulence and absorption of seawater are two important factors affecting the signal transmission quality of underwater optical communication link. Here, we study the channel capacity and bit error rate of an underwater extinction communication link with
