Gaussian channel transmission of images and audio files using cryptcoding

Random codes based on quasigroups (RCBQ) are cryptcodes, i.e. they are error-correcting codes, which provide information security. Cut-Decoding and 4-Sets-Cut-Decoding algorithms for these codes are defined elsewhere. Also, the performance of these codes f ...

Inpainting of Long Audio Segments With Similarity Graphs

Nathanaël Perraudin

We present a novel method for the compensation of long duration data loss in audio signals, in particular music. The concealment of such signal defects is based on a graph that encodes signal structure in terms of time-persistent spectral similarity. A sui ...

A Sub-μW/Channel, 16-Channel Seizure Detection and Signal Acquisition SoC Based on Multichannel Compressive Sensing

Alexandre Schmid, Reza Ranjandish

An accurate 16-channel seizure detection system-on-chip is presented, which is based on extracting features from the compressed recorded data using multichannel compressive sensing (MCS). MCS is used to reduce the transmission data rate of sparse biologica ...

Experimental evaluation of speech enhancement methods in remote microphone systems for hearing aids

Hervé Lissek, Gilles André Courtois, Vincent Pierre Olivier Grimaldi, Ina Kodrasi

Enhancing speech intelligibility for hearing-impaired subjects in complex acoustic conditions is still a challenging topic of research. To mitigate the detrimental effects of background noise and reverberation, current hearing instruments incorporate vario ...

Effects of erbium-doped fiber amplifier induced pump noise on soliton Kerr frequency combs for 64-quadrature amplitude modulation transmission

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Fatemeh Alishahi, Amirhossein Mohajerin Ariaei, Arne Kordts, Maxim Karpov, Ahmad Fallahpour, Lin Zhang

We experimentally investigate the effects of erbium-doped fiber amplifier induced pump noise on soliton Kerr frequency combs for 64-quadrature amplitude modulation (QAM) transmission. We find that the optical carrier-to-noise ratios (OCNRs) of the comb lin ...

An Eight lanes 7Gb/s/pin Source Synchronous Single-Ended RX with Equalization and Far-End Crosstalk Cancellation for Backplane Channels

Yusuf Leblebici, Alessandro Cevrero, Lukas Kull, Volkan Cevher, Thomas Toifl, Cosimo Aprile

This paper presents a versatile crosstalk cancellation scheme for single-ended multi-lane backplane links. System-level investigations show that a scheme, which combines analog filters and decision-feedback crosstalk compensation on the receiver (RX) side ...
