The method of modeling and designing adaptive inverse controllers is studied , and the structure coupled with least - mean - square ( lms ) algorithm for controlling a linear plant is discussed 首先研究了對象建模和控制器設(shè)計的方法,討論了用lms算法實現(xiàn)的濾波器結(jié)構(gòu)。
In addition , the beamforming techniques for cdma systems are discussed emphatically . the algorithm based on code filtering is deduced in detail theoretically , and the performances such as convergence and bit error rate ( ber ) are simulated . meanwhile , we improve a decision - projected algorithm based on least - mean - square ( lms ) error 論文重點討論了cdma系統(tǒng)的波束形成技術(shù),在理論上詳盡地推導(dǎo)了基于擴頻碼濾波的波束形成算法,對其收斂性、誤碼率等進行了計算機仿真;針對基于最小均方( lms )誤差的一種判決映射算法進行了改進。
