And then modulation scheme is determined adaptively according to the power allocated to each subchannel. The advantage of the M-CAP scheme is that it combines power allocation and adaptive modulation while maintaining a large capacity. We demonstrate by computer simulations that the proposed M-CAP scheme can significantly improve system performance compared with the traditional schemes.展开更多

Requiring adjustment of income distribution gap is growing from various aspects and this article attempts to investigate theoretical level of influence in government regulating income distribution gap, mainly involving the government and the blur, efficiency loss in market boundaries, the deficit effects and other aspects of government failure. We strive to prevent the possible deviations of goverrmaent in the implementation of the regulation, expect to deepen understanding and promote the practice for some benefit.展开更多

What follows is an analysis of personal adjustment tax income from the proportion of Gini coefficient, Engels coefficient and salaried class of personal income tax, and an explanation of problems and countermeasures of salaried class expense deduction standard, tax rate design, high-income crowd tax regulation.展开更多
