in wireless channel the noise has a zero mean. this channel property can be used in the enhancement of the noise performance in the digital receivers by oversampling the received signal and calculating the decision variable based on the time average of more than one sample of the received signal. the averaging process will reduce the effect of the noise in the decision variable that will approa...

Oversampling techniques offer several advantages for the implementation of high-resolution analog-to-digital (A/D) converters in VLSI technologies. This paper examines the application of oversampling techniques to A/D conversion at rates exceeding 1 MHz. A cascaded multibit sigma-delta (2A) modulator that substantially reduces the oversampling ratio required for 12-b conversion while avoiding s...

This paper reviews standard oversampling strategies as performed in the multiscale finite element method (MsFEM). Common to those approaches is that the oversampling is performed in the full space restricted to a patch including coarse finite element functions. We suggest, by contrast, performing local computations with the additional constraint that trial and test functions be linear independe...

Blind-oversampling adaptive oversample-level decision feedback-equalized (DFE) receiver is presented for use in global onchip serial links. The blind oversampling is adopted to avoid receiver synchronization for reliable channel data reception, and the adaptive oversample-level DFE is used to reduce data-dependent jitter and ease oversampling data recovery regardless of PVT variations. Test res...

It is hard to trust any data entry on online websites as some may be malicious, and gather for illegal or unintended use. For example, bank login credit card information can misused financial theft. To make users aware of the digital safety websites, we have tried identify learn pattern a dataset consisting features malicious benign websites. We treated problem differentiation between classific...

Breast cancer is non-skin that caused by several factors, including glandular ducts, cells, and breast support tissue, except for the skin of breast. if not treated immediately will be fatal sufferer, so early detection important patient's safety. The success depends on right diagnosis. Measurement accuracy a diagnosis can assisted statistical methods, namely classification. K-Nearest Neighbor ...

In this research, we propose an online basis enrichment strategy within the framework of a recently developed constraint energy minimizing generalized multiscale discontinuous Galerkin method. Combining technique oversampling, one makes use information current residuals to adaptively construct functions in stage reduce error approximation. A complete analysis method is presented, which shows pr...

It is advantageous to use oversampling techniques with either ∆Σ or broadband data converters in both wireline and wireless digital receivers. This paper discusses the oversampling techniques for all-digital implementation of symbol timing recovery in digital receivers. The idea of oversampling techniques for timing recovery is to adjust the timing phases while decimating the oversampled signal...
