This paper proposes an new iterative method to recover the signals corrupted by impulsive noise in MIMO-OFDM systems over In-home PLC. In this iterative technique, preliminary decisions are made to get the impulsive noise detection algorithm for finding the locations and amplitudes of the impulses, and then signal estimation block for approximation the signals for two-branch 2*2 MIMO-OFDM at th...

Abstract. In Magnetic Resonance Imaging (MRI) room, strong acoustic noise during the scan not only creates harmfully annoying environment but also interferes with brain activation response. The presence of reverberation in the MRI environment interferes with efficient noise canceling techniques. In this paper, we present a blind dereverberation method for estimating the broadband MRI acoustic n...

We describe an offset-canceling low-noise lock-in architecture for capacitive sensing. We take advantage of the properties of modulation and demodulation to separate the signal from the dc offset and use nonlinear multiplicative feedback to cancel the offset. The feedback also attenuates out-of-band noise and further enhances the power of a lock-in technique. Experimentally, in a 1.5m BiCMOS ch...

INTRODUCTION Helicopter cockpits are very noisy and this noise must be reduced for effective communication. The standard U.S. Army aviation helmet is equipped with a noise-canceling acoustic microphone, but some ambient noise still is transmitted. Throat microphones are not sensitive to air molecule vibrations and thus, transmittal of ambient noise is reduced. It is possible that throat microph...

CONTEXT Anesthesiologists use various medications to provide surgical patients with pain relief in the postoperative period. Other modalities, such as music, could be used in conjunction with opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) to decrease pain and lower heart rate and blood pressure. Our hypothesis was that patients listening to jazz in a postanesthesia care unit (PACU) w...

This article presents a 23–40-GHz phased-array receiver (RX) capable of reconfiguring to achieve fine phase step and high gain range. Such RX consists 14-bit phase-gain manager wideband noise-canceling low-noise amplifier (NCLNA). The proposed includes two 7-bit variable amplifiers (VGAs) in radio-frequency (RF) domain, pairs mixers, sign-map (VGSM) circuits intermediate-frequency (IF) domain. ...

After February 24th, 2022, the Western society, mainly U.S. and European countries, demonstrated a general trend that can be considered “canceling” Russia in response to its special military operation Ukraine (western companies leaving Russia, athletes under Russian flag being excluded from international sportive events, Netflix suspending services clients, etc.). Among other examples, culture ...
