Since optical links are easily blocked by obstacles in the environment, they have been considered difficult to directly perform wireless communications. However, reconfigurable intelligent surfaces (RISs), as a new type of digital coding meta-materials, can significantly improve coverage communication establishing links. We propose controllable multi-branch system based on RISs. By setting up multiple RISs artificial channels built performance and reduce outage probability. In this paper, we...
Oriented to the point-to-multipoint free space optical communication (FSO) scenarios, this paper analyzes micro-mirror array and phased array-type intelligent reflecting surface (OIRS) in terms of control mode, power efficiency, beam splitting. We build physical models two types OIRSs. Based on models, closed form solution OIRSs' output density distribution along with their algorithms have been derived. Then we propose splitting multi-beam allocation for The channel fading FSO system...
In this paper, we propose an enhanced reconstruction method of NR-LDPC codes for ultra-high capacity Petahertz (PHz) communications. We redesign the protograph by partially increasing column weights under BDD structure in parity part and adjusting information where single diagonal Raptor-like is reasonably maintained to guarantee waterfall performance linear complexity encoding. After that, simplified EMPEG algorithm used optimize shifting values non-zero positions new protograph, so that...

Related simulations have been established verify accuracy models...
Traffic flow prediction is one of the key research directions intelligent transportation systems, and accurate traffic can effectively reduce congestion improve road utilization. With rapid development artificial intelligence, many machine learning deep models have been successfully applied to prediction. Due factors influencing flow, extremely complex nonlinear relationships between these factors, temporal spatial correlations considered a challenging problem. In this paper, new...
In this paper, we propose an optimization scheme of quasi-cyclic low-density parity-check (QC-LDPC) codes based on evolutionary algorithm, the Genetic Algorithm (GenAlg). By changing positions and shift values non-negative entries in base matrix, optimized can achieve better decoding performances. The construction matrix compatible for multiple lengths with different lifting sizes is discussed a statistic metric used to measure effectiveness introduced quantitatively evaluate performances...
