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 ...

Genetic Algorithm Assisted Minimum Bit Error Rate Multiuser Detection in Multiple Antenna Aided OFDM
, 2004 The family of minimum bit error rate (MBER) multiuser detectors (MUD) is capable of outperforming the classic minimum mean-squared-error (MMSE)MUDin term of the achievable bit-error rate (BER) owing to directly minimising the BER cost function.

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 ...

Bit error rate estimation for turbo decoding
IEEE Transactions on Communications, 2003 In this paper we propose a method for on-line estimation of bit error rate during turbo decoding. We model the log-likelihood ratios as a mixture of two Gaussian random variables and derive estimators for the mean and variance of these distributions based on a maximum-likelihood approach. The parameter estimates are then employed to calculate the cross-

Adaptive minimum error-rate filtering design: a review
, 2008 Adaptive filtering has been an enabling technology and has found ever-increasing applications in various state-of-the-art communication systems. Traditionally, adaptive filtering has been developed based on the Wiener or minimum mean square error (MMSE ...

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.
