Direction Finding in Partly Calibrated Arrays Exploiting the Whole Array Aperture
Guangbin Zhang, Tianyao Huang, Yimin Liu +2
We consider the problem of direction finding using partly calibrated arrays, a distributed subarray with position errors between subarrays. The key challenge is to enhance angular…
Hyper-Parameter Auto-Tuning for Sparse Bayesian Learning
Dawei Gao, Qinghua Guo, Ming Jin +2
Choosing the values of hyper-parameters in sparse Bayesian learning (SBL) can significantly impact performance. However, the hyper-parameters are normally tuned manually, which is…
Compressed IF-TEM: Time Encoding Analog-To-Digital Compression
Saar Tarnopolsky, Hila Naaman, Yonina C. Eldar +1
An integrate-and-fire time-encoding-machine (IF-TEM) is an energy-efficient asynchronous sampler. Utilizing the IF-TEM sampler for bandlimited signals, we introduce designs for tim…
Signal Detection in MIMO Systems with Hardware Imperfections: Message Passing on Neural Networks
Dawei Gao, Qinghua Guo, Guisheng Liao +4
In this paper, we investigate signal detection in multiple-input-multiple-output (MIMO) communication systems with hardware impairments, such as power amplifier nonlinearity and in…
Analog Compressed Sensing for Sparse Frequency Shift Keying Modulation Schemes
Kathleen Yang, Diana C. Gonzalez, Yonina C. Eldar +1
There is a growing interest in signaling schemes that operate in the wideband regime due to the crowded frequency spectrum. However, a downside of the wideband regime is that obtai…
Nonlinear Waveform Inversion for Quantitative Ultrasound
Avner Shultzman, Yonina C. Eldar
Due to its non-invasive and non-radiating nature, along with its low cost, ultrasound (US) imaging is widely used in medical applications. Typical B-mode US images have limited res…
