decision n. 1.決定。 2.判決。 3.決議。 4.決心;決斷。 5.【美拳】(根據(jù)分?jǐn)?shù)而不是根據(jù)擊倒對(duì)方做出的)裁判。 a man of decision 有決斷力的人,果斷的人。 come to a decision 做出法定。 decision by majority 取決于多數(shù)。 give a decision for [against] 判決對(duì)…有利[不利]。 with decision 斷然。 decision table (列出對(duì)付某問題各項(xiàng)可選擇辦法的)決策表。
And improve the performance by use of the decision feedback equalization 并提出了決策反饋均衡對(duì)系統(tǒng)性能的改善。
Then we focus on decision feedback equalization ( dfe ) algorithm which is widely used in mimo signal detection . subsequently , a minimum mean squared error ( mmse ) detector based on wl detection combined with the decision feedback strategy for ca - mimo is derived . meanwhile , the issue that how to use wl detection in da - mimo system is discussed and a solved project is also presented 本文第四章在介紹了寬線性檢測(cè)技術(shù)的基礎(chǔ)知識(shí)之后,著重針對(duì)mimo信號(hào)檢測(cè)算法中使用廣泛的反饋判決檢測(cè)算法,提出了一種基于最小均方誤差準(zhǔn)則的寬線性反饋判決集中式mimo信號(hào)檢測(cè)算法;同時(shí),結(jié)合第三章的內(nèi)容,對(duì)分布mimo信號(hào)如何采用寬線性檢測(cè)提出了一套解決方案,通過計(jì)算機(jī)仿真,給出了幾種分布mimo檢測(cè)算法的性能;結(jié)果表明,在采用最優(yōu)檢測(cè)順序的情況下,兩
In this proposed algorithm , the phase rotation can be compensated using higher order statistics , nonlinear transform of equalizer outputs , and decision feedback algorithm , the faster convergent speed can be obtained by introducing sign algorithm , and the mse can be reduced via employing decision feedback equalization algorithm 該算法充分利用高階統(tǒng)計(jì)量所包含的相位信息、均衡器輸出信息的非線性變換及判決反饋算法來補(bǔ)償相位旋轉(zhuǎn);利用符號(hào)算法可以減少計(jì)算量的特點(diǎn)來加快收斂速度;利用判決反饋濾波器的性能來減小均衡器輸出的均方誤差。
