The research of multipath parameter estimation algorithms and accomplishing them with software . to estimate multipath parameters , multipath delays must be estimated by code filtering in advance 信道多徑參數估計算法的研究和軟件實現在估計多徑參數時,首先使用碼濾波方法估計出信號的多徑時延。
Firstly , the steering vector of mainpath of desired user is estimated by using code filtering method , then dummy signals are introduced , main lobe of wave is built by using the steering vector of mainpath of desired user and side lobes is constrained by using dummy signals 該方法首先利用碼濾波的方法估計期望用戶主徑的波達方向,然后引入虛擬信號,利用期望用戶主徑的波達方向形成波束的主瓣,并利用虛擬信號抑制旁瓣。
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系統的波束形成技術,在理論上詳盡地推導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。
