What does fiscal equalization effects the fiscal effort of local government ? can we estimate the intergovernmental fiscal relation virtually and propose some advices on public policy 通過對財政競爭和均等化的分析,能否對目前的政府間財政關系做出一個客觀的評價,并提出相關政策建議
The proposed algorithm lows the complexity by choosing decision delay in advance and then making solution of the equalizer tap coefficient , a new decision delay choice method is proposed , solution by using weight method , diagonal matrix transform , z extension and a new energy restrictive condition which restrains noise enhance , a new decision delay choice method is proposed , the simulation result shows that the proposed algorithm has better equalization effect and enhanced performance comparing to the general mmse algorithm , simulation research on the precision and dynamic scope of parameters in digital realization time domain equalization algorithm , design software and hardware of time domain equalizer . fourthly , there exist a lot of interfere in dsl line , especially , dsl works in multi - user mode , the near end interference is serious 通過先選擇判決時延,再進行時域均衡器抽頭系數求解的方法降低了時域均衡計算復雜度;對于均衡器抽頭系數的求解使用了加權技術,通過對角矩陣變換, z擴展,使用不同的能量約束條件對算法求解,結果表明這種約束有效的抑制了噪聲增強,與常用刪se比較,該算法有更佳的均衡效果,算法性能得到了提高:論文還對數字化實現時域均衡算法中每一部分參數的精度、變量的動態(tài)范圍進行了模擬研究,對時域均衡的軟硬件實現進行了設計。
In this case , time domain equalization algorithm based on channel estimation will influence equalization effect if choosing noise sensitive algorithm to estimate channel , so it is necessary to adopt an anti - noise and high estimation precision estimation algorithm . in this dissertation , a new time domain equalization algorithm based on low rank hankel approximati Dsl線路實際工作環(huán)境存在各種干擾,尤其當多用戶時,串音干擾很嚴重,對于采用基于信道估計的時域均衡算法,如果使用對噪聲敏感的算法進行信道估計,必然影響均衡效果,因此需要采用具有抗噪聲,估計精度高
