And improve the performance by use of the decision feedback equalization 并提出了決策反饋均衡對系統(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技術(shù)的基礎(chǔ)知識之后,著重針對mimo信號檢測算法中使用廣泛的反饋判決檢測算法,提出了一種基于最小均方誤差準則的寬線性反饋判決集中式mimo信號檢測算法;同時,結(jié)合第三章的內(nèi)容,對分布mimo信號如何采用寬線性檢測提出了一套解決方案,通過計算機仿真,給出了幾種分布mimo檢測算法的性能;結(jié)果表明,在采用最優(yōu)檢測順序的情況下,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償相位旋轉(zhuǎn);利用符號算法可以減少計算量的特點來加快收斂速度;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。
