In this paper, the convergence behavior of linear parallel interference cancellation is investigated. Especially the so-called ping-pong effect, where the bit-error rate performance is found to oscillate between two different convergence patterns is studied in detail. This effect is shown to be a direct consequence of the extreme eigenvalues of the correlation matrix, allowing for an analytical...

Enzymes are biodegradable catalysts naturally present in living organisms. can accelerate biochemical reactions by reducing the activation energy, and they not consumed during reaction processes. Numerous applications of enzymes have been developed biotechnology, industry, medicine, pharmaceuticals, food processing, biofuels, so on. In this study, we develop a mathematical model describing enzy...

Memory bandwidth is frequently a limiting factor in the design of high-speed switches and routers. In this paper, we introduce a buffering scheme called ping-pong buffering, that increases memory bandwidth by a factor of two. Ping-pong buffering halves the number of memory operations per unit time, allowing faster buffers to be built from a given type of memory. Alternatively, for a buffer of g...

This paper presents a novel method for absolute three-dimensional (3D) shape measurement that does not require conventional temporal phase unwrapping. Our proposed method uses a known object (i.e., a ping-pong ball) to provide cues for absolute phase unwrapping. During the measurement, the ping-pong ball is positioned to be close to the nearest point from the scene to the camera. We first segme...
