Communications among vehicles is an important field of study for transportation systems. Vehicular Ad Hoc Networks (VANETs) are appropriate networks that can be applied to intelligent transportation systems (Nadeem, 2006). VANET is based on short-range wireless communications among vehicles and is built on-the-fly and do not need any investment, except the wireless network interfaces that will ...
In this paper, we focus on the design and analysis of Analog Fountain Code (AFC) for short packet communications. We first propose a density evolution (DE) based framework, which tracks probability function messages exchanged between variable check nodes AFC in belief propagation decoder. Using proposed DE formulate an optimisation problem to find optimal code parameters, including weight-set, ...
We investigate fixed-point aspects and time-domain ASIC implementations of CD compensation. An optimized implementation gives significant power dissipation reduction for short links, with further reduction if pulse shaping is considered. OCIS codes: (060.1660) Coherent communications; (060.4510) Optical communications
