The tax system in Russia as a differentiation factor of the living standard of the population by I. V. Snimshchikova, K. E. Shamray

“…The assessment and views of both domestic and foreign economic scientists on the quality and efficiency of the use of the tax system and the tax rate are presented. Mathematical calculations were carried out, on the basis of which it was proposed to reduce the income tax rate for low-income citizens, the introduction of a selective tax, the development of which contributes to improving the quality of social services provided by the state. …”

Improved optical generalized spatial modulation in Málaga turbulent channel by Hui ZHAO, Weiwen MA, Jin LI, Wenchao DENG, Hui WAN, Tianqi ZHANG, Yuanni LIU

“…Aiming at the problems of space resource waste and error bit performance limitation caused by fixed optical antenna combination set used in traditional optical generalized spatial modulation (OGSM), an improved scheme based on low complexity adaptive optical antenna combination set selection algorithm was proposed.First, the Euclidean distance matrix between optical antenna combinations was calculated using channel state information.Then, based on the principle of Euclidean distance equivalence and the idea of maximum norm antenna selection, the optical antenna combination with poor channel state was deleted, and the final reserved optical antenna combination was the optimal optical antenna combination set in the current state.The traversal of all optical antenna combinations was avoided and the complexity of the algorithm was reduced to a large extent.The simulation results show that the BER performance of the improved OGSM scheme outperforms the conventional OGSM under different conditions.…”
