Noise Cancellation with Static Mixtures of a Nonstationary Signal and Stationary Noise
We address the problem of cancelling a stationary noise component from its static mixtures with a nonstationary signal of interest. Two different approaches, both based on second-order statistics, are considered. The first is the blind source separation (BSS) approach which aims at estimating the mixing parameters via approximate joint diagonalization of estimated correlation matrices. Proper e...
متن کاملAdaptive-Filtering-Based Algorithm for Impulsive Noise Cancellation from ECG Signal
Suppression of noise and artifacts is a necessary step in biomedical data processing. Adaptive filtering is known as useful method to overcome this problem. Among various contaminants, there are some situations such as electrical activities of muscles contribute to impulsive noise. This paper deals with modeling real-life muscle noise with α-stable probability distribution and adaptive filterin...
متن کاملThe Signal and Noise Analysis of Direct Conversion EHM Transceivers
A direct conversion modulator-demodulator with even harmonic mixers with emphasis on noise analysis is presented. The circuits consist of even harmonic mixers (EHMs) realized with antiparallel diode pairs (APDPs). We evaluate the different levels of I/Q imbalances and DC offsets and use signal space concepts to analyze the bit error rate (BER) of the proposed transceiver using M-ary QAM schemes...
متن کاملA Highly LinearLNA with Noise Cancellation for 5.8–10.6 GHz UWB Receivers
This paper presents a new ultra-wideband LNA which employs the complementary derivative superposition method in noise cancellation structure. A pMOS transistor in weak inversion region is employed for simultaneous second- and third-order distortion cancellation. Source-degeneration technique and two shunt inductors are added to improve the performance at high frequencies. The degeneration induc...
متن کاملA Novel Cancellation Path Modeling Signal for Active Noise Control
A new on-line cancellation path modeling signal for active noise control is proposed in this paper. The signal is based on the spectrum of the disturbance signal, and is especially useful for the cancellation path modeling in active noise control when the disturbance signal is tonal. It is shown that using the proposed signal as the perturbation signal in modeling can significantly reduce the m...
