A factor graph approach to joint iterative data detection and channel estimation in pilot-assisted IDMA transmissions
We consider a pilot-assisted interleave-division multiple access (IDMA) system transmitting over block-fading channels. We describe this system in terms of a factor graph and use ...

Metodology for selecting the best suitable bottleneck detection method
Focusing on process constraints (or bottlenecks) is how companies are improving productivity, decreasing response times. However, a bottleneck is not easily detectable, especially...

An aliasing detection algorithm based on suspicious colocalizations of Fourier coefficients
We propose a new algorithm to detect the presence and the localization of aliasing in a single digital image.Considering the image in Fourier domain, the fact that two frequencies...
