This paper analyzes the performance of the linear parallel interference cancellation (LPIC) multiuser detector in a synchronous multiuser communication scenario with binary signaling, nonorthogonal multiple access interference, and an additive white Gaussian noise channel. The LPIC detector has been considered in the literature lately due to its low computational complexity, potential for good ...

The X-ray detector is the heart of a digital mammography system. Its improved characteristics of dynamic range and signal-to-noise ratio provide inherent advantages over screen-fi lm technology. Detector technologies used for digital mammography can be distinguished by the acquisition geometry into scanning or full-fi eld detectors, by energy conversion mechanism into phosphor-based and nonphos...

The purpose of this study was to determine the performance of low-dose computed tomography (CT) scanning with integrated circuit (IC) detector in defining fine structures of temporal bone in children by comparing with the conventional detector. The study was performed with the approval of our institutional review board and the patients' anonymity was maintained. A total of 86 children<3 years o...

An appropriate adaption of the decision boundaries of the well-known signal space detector (SSD) yields a detector that whitens the input noise in the detector forward path. This new detector, called a whitening signal space detector (WSSD), offers higher reliability without increasing the dimensionality of the signal space. A WSSD can be designed by applying a transformation into the ordinary ...

This paper defines the Non-Blocking Atomic Commitment problem in a message-passing asynchronous system and determines a failure detector to solve the problem. This failure detector, which we call the modal failure detector star, and which we denote by M*, is strictly weaker than the perfect failure detector P but strictly stronger than the eventually perfect failure detector ◇P. The paper shows...

Nonparametric detection of a zero-mean random signal in additive noise is considered. The locally optimum detector based on signs and ranks of observations is derived, for good weak-signal detection performance under any specified noise probability density function. This detector is shown to have interesting similarities to the locally optimum detector for random signals. It may also be viewed ...

Although the approximations based on the central limit theorem (CLT) for the detection probability (Pd) of the energy detector and of its more generalized cousin, the p-norm detector, are accurate for large sample sizes, their accuracy is poor otherwise. A recent work has addressed this problem by developing a cube-of-Gaussian approximation (CGA). However, CGA may not be the only option and thu...

Motion perception is one of the mod important aspect of the biological visual system, @om which we get a lot of infort?tation of the natural world. From the physiological and anatomical study on biological vision system, it is shown tliat the perception of two dimentional (20) t?rotion is in two steps: one dimentional (ID) motion detection arid I D motion information fusion. This paper we pay a...

One of the major physics topics of the CBM experiment is the study of the production of open charm in nucleusnucleus collisions at FAIR energies. For this purpose, the CBM Collaboration is planning to use a high-performance Micro-Vertex Detector (MVD) based on Monolithic Active Pixel Sensors (MAPS) [1]. CBM running conditions call for a MVD with high granularity, radiation tolerance, and readou...
