Noise shaping in neural populations. [PDF]

Phys Rev E Stat Nonlin Soft Matter Phys, 2009
Many neurons display intrinsic interspike interval correlations in their spike trains. However, the effects of such correlations on information transmission in neural populations are not well understood. We quantified signal processing using linear response theory supported by numerical simulations in networks composed of two different models: One ...

Recognition of spectrally shaped speech in speech-modulated noise: Effects of age, spectral shape, speech level, and vocoding [PDF]

JASA Express Letters, 2023
This study examined the recognition of spectrally shaped syllables and sentences in speech-modulated noise by younger and older adults. The effect of spectral shaping and speech level on temporal amplitude modulation cues was explored through speech ...

Joint Shaping of Geometry and Probability based on Mutual Information Neural Estimation

Guangtongxin yanjiu, 2022
In view of the problem that quadrature amplitude modulation has 1.53 dB capacity gap at the Shannon limit in high signal noise ratio, the paper proposes a joint shaping method of geometry and probability based on mutual information neural estimation ...

Compensating Processing Delay in Excess of One Clock Cycle in Noise Shaping Loops Without Altering the Filter Topology

IEEE Access, 2021
This work presents an analytical method to design a stable loop filter for a noise shaper with parasitic delays or poles in the loop. This method does not require an increase in the order of the loop or extra feedback paths and keeps the original poles ...
