Abstract:
In this paper, a novel Artificial Neural-Network (ANN) based multi-sensor multi-band adaptive signal-processing scheme is described for enhancing acoustic-speech corrupted by real noise and reverberation. Numerically robust adaptation-algorithms are employed for the ANN based sub-band filters; and, new simulation experiments are reported using real-reverberant automobile data which demonstrate that the proposed speech-enhancement system is capable of outperforming conventional linear filtering-based wide-band and multi-band noise-cancellation schemes.

Abstract:
In this paper, an ultra-wide band (UWB) low noise amplifier (LNA) is implemented by using 90nm RF CMOS technology. The designed LNA achieves high flat band gain (S21) and low noise figure (NF) in the frequency of interest. The proposed LNA operates in the frequency range of 3GHz to 8GHz. In this work, wide band matching is achieved by designing common gate configuration at the input stage. The current reuse and noise cancellation techniques are introduced to improve flat band gain and minimize both noise figure and power consumption. The noise figure is improved by cancelling dominant noise so

Abstract:
Abstract In-band full-duplex (IBFD) technology can potentially improve spectrum efficiency compared to half-duplex technology. The cancellation of the self-interference (SI) signal is the key to implementing the IBFD system to achieve accurate detection of the signal of interest. In this work, we fully account for the effect of IQ imbalance, phase noise (PN), additional Gaussian white noise (AWGN), and the nonlinear caused by the RF impairments of power amplifier, and adopt the method of canceling SI signal combined with the propagation, analog, and digital domain to cancel the SI signal, but

Abstract:
AbstractFor a frequency‐division duplex (FDD) wide‐band code‐division multiple‐access (WCDMA) system, transmit (TX) signal leakage at the receiver input degrades the receiver performance. To cancel this TX leakage, a frequency selective feedback was previously proposed, but it had an unpredictable feedback loop characteristic due to the uncertainty of the duplexer impedance. This paper presents a new method to achieve TX leakage cancellation regardless of the duplexer impedance. In addition, a local oscillator (LO) phase shift technique is proposed to apply this method for multi‐band. A receiv

Abstract:
This paper introduces a Ku-band fully differential low-power high-input 1 dB compression point (P1dB) low-noise amplifier (LNA). A fully differential structure is employed to enhance the input P1dB, common-mode noise rejection, and second harmonic cancellation. The first stage adopts large transistors and is optimized for power consumption and noise figure (NF). The output stage is designed with class AB bias, resulting in improved P1dB, power consumption, and linearity. The proposed two-stage fully differential common-source (CS) LNA was implemented using 65 nm bulk complementary metal oxide

Abstract:
A low-noise amplifier (LNA) design with the operation of concurrent dual-band for Global Navigation Satellite System (GNSS) receivers with single channel is presented in this work. This LNA structure has an inductively degenerated cascode architecture and is pseudo-differential, operating at two frequencies simultaneously (1.2 GHz and 1.57 GHz). Two noise reduction/cancellation techniques, using load capacitor and feedforward path, respectively, are proposed resulting in an excellent improvement in the noise figure (NF). The input matching circuit uses both series and parallel resonant compone

Abstract This experimental study explores the acoustic signal generated when water/sand slurry flows through perforations in the frequency domain. The goal is to identify the proppant presence on distributed acoustic sensors (DAS), and possibly to estimate proppant concentration distribution during a multi-stage fracture treatment using DAS monitoring data. We have studied whether sand-related signals can be distinguished from water flow signals in the frequency domain, what are the frequency components of signals for proppant, and how do proppant concentration or other parameters affect the p
