Attitude determination and control for centrifugal tether deployment on the ESTCube-1 nanosatellite; pp. 242–249 [PDF]
Proceedings of the Estonian Academy of Sciences, 2014 This paper presents the design, development, and pre-launch characterization of the ESTCube-1 Attitude Determination and Control System (ADCS). The design driver for the ADCS has been the mission requirement to spin up the satellite to 360 deg à sâ1 ...

Nonlinear Precoding for Multipair Relay Networks With One-Bit ADCs and DACs
IEEE Signal Processing Letters, 2018 We consider a multipair half-duplex relay communication network, where the relay is deployed with one-analog-to-digital converters and one-bit digital-to-analog converters. To suppress the interpair interference and quantization artifacts, we propose nonlinear precoding schemes to forward the quantized signals at the relay. We first present a technique

Listening to Music Through Hearing Aids: Potential Lessons for Cochlear Implants
Trends in Hearing, 2022 Some of the problems experienced by users of hearing aids (HAs) when listening to music are relevant to cochlear implants (CIs). One problem is related to the high peak levels (up to 120 dB SPL) that occur in live music. Some HAs and CIs overload at such

Convexity of the Capacity of One-Bit Quantized Additive White Gaussian Noise Channels
Mathematics, 2022 In this study, the maximum error-free transmission rate of an additive white Gaussian noise channel with a symmetric analog-to-digital converter (ADC) was derived as a composite function of the binary entropy function, Gaussian Q-function, and the square

Semi-Supervised Learning Detector for MU-MIMO Systems with One-Bit ADCs [PDF]
2019 IEEE International Conference on Communications Workshops (ICC Workshops), 2019 We study an uplink multiuser multiple-input multiple-output (MU-MIMO) system with one-bit analog-to-digital converters (ADCs). In this system, we recently proposed a supervised-learning (SL) detector by modeling a non-linear end-to-end system function into a parameterized Bernoulli-like model.
