This paper revisits several methods used in iterative decoders to improve the performance of the LTE Turbo code for small information blocks. By considering the iterative decoder as a chaotic system, some explanations are given on the unexpected behavior of several post-processing algorithms. A "dither-inspired" algorithm, called blind candidate de...
Non-binary Turbo codes have been shown to outperform their binary counterparts in terms of error correcting performance yet the decoding complexity of the commonly used Min-Log-MAP algorithm prohibits efficient hardware implementations. In this work, we apply for the first time the recently proposed Local SOVA algorithm for decoding non-binary Turb...
This is a special issue in cooperation with EuroSPI (www.eurospi.net). EuroSPI represents a large international network of renowned experts and annual European conference series running successfully since its foundation in 1994. From 2013 onwards, an international functional safety and from 2016 onwards a functional safety and cybersecurity worksho...

This paper presents a wide-angle scanning multibeam Planar Inverted-E Antenna (PIEA) array for V2X communication. The compact 4-element PIEA array is designed with 0.3o spacing, which achieves 900 wide-angle scanning when a 135 phase shift is applied obtained using a 4x4 Butler Matrix (BM). The closeness of the array elements causes high mutual cou...

The computation of the scattered field from an object and its Radar Cross Section (RCS) can be a very timeconsuming task and may also require a high memory. Indeed, as the problem’s size scales with the number ofedges NEdge of the object, the need of fast and memory-efficient algorithm arose to solve high frequency problems.Thus, to overcome this i...

Since the emergence of the coronavirus disease (COVID-19), more than 165 million people have been infected all around the world (as of May 2021). The COVID-19 virus is highly contagious, especially in large crowded spaces. To prevent the infection and slow the transmission of the virus, the World Health Organization recommends wearing a mask, washi...
