Reliable co-channel bidirectional transmission in wireless networks is moving towards reality by employing the emerging full-duplex (FD) technology. Enhanced by FD-capable nodes, a future wireless network can be made up merely with pairs of bidirectional communicating nodes where each pair occupies a block of orthogonal resource to avoid interference, referred to as pure-FD system. In this paper,...
According to the infrared imaging mechanism, this paper proposes a Nonuniformity Correction(NUC) enhancement method to improving the image quality of Infrared system. analyzing the connection between the responsivety and the nonuniformity of each pixel on infrared focal plane array (IRFPA), gain and offset coefficients were updated gradually, calculating the image of a scene threshold gray level information,...
Aiming at tracking Closely-Spaced Objects (CSOs) from image observations, a new method using the Probability Hypothesis Density (PHD) filter is proposed. To circumvent the unresolved measurements problem, a detection process is used firstly to extract the connected sets of object pixels that likely correspond to the unresolved targets of interest. Then the representative measurements are constructed...
Readout noise of RF impedance analyzer and LCR meter are observed and analyzed with narrow bandwidth noise theory. The difference between theory analysis and actual measurement results is shown. The effect of impedance measurement format on noise is discussed at last.
This paper presents a 1.25Gb/s high gain optical receiver pre-amplifier featuring a wide dynamic range in 0.35µm standard CMOS. The designed amplifier is configured on three identical stages, incorporating the automatic gain control (AGC) technique to achieve a wide input dynamic range and a good noise performance. The post-simulations demonstrate the transimpedance gain of 80.5dBΩ, the −3dB bandwidth...
Background subtraction in highly dynamic scenes has been a critical challenge for traditional pixel-wise background models which perform poorly when the background has dynamic textures. In this paper, we consider background modelling in a spatial perspective and make an attempt to exploit more information from the outputs of pixel-wise model. We propose a background subtraction scheme using adaptive...
Parabolic Radon transform (PRT) is one of the most effective methods to eliminate multiple. Based on model study and programming, the article shows the physical signification of FPRT firstly, then presents the theories and implementation processes about the forward and inverse parabolic Radon transform infrequency domain. It also discusses the aliasing in radon domain, the stability of radon transform,...
