【摘要】：針對(duì)每個(gè)移動(dòng)終端進(jìn)行動(dòng)態(tài)的三維波束賦形,為了使三維波束主瓣對(duì)準(zhǔn)期望用戶并且在干擾用戶方向形成零陷,構(gòu)建了均勻平面陣的二維陣列信號(hào)模型,研究了基于最小均方誤差算法的全局自適應(yīng)算法,并在此基礎(chǔ)上提出了基于降維的局部自適應(yīng)算法.2種自適應(yīng)三維波束賦形算法可以動(dòng)態(tài)地調(diào)整陣列單元的權(quán)值,自適應(yīng)地改變天線陣列的方向圖,為用戶提供實(shí)時(shí)的跟蹤服務(wù).仿真結(jié)果表明,在一定數(shù)量的陣列天線單元的條件下,2種算法均可以實(shí)現(xiàn)針對(duì)期望用戶的自適應(yīng)三維波束賦形.
[Abstract]:For each mobile terminal, dynamic three-dimensional beamforming is carried out. In order to align the main lobe of the three-dimensional beam to the desired user and to form a zero trapping in the interference direction of the user, a two-dimensional array signal model of uniform plane array is constructed.The global adaptive algorithm based on minimum mean square error (MSE) algorithm is studied. Based on this, a local adaptive algorithm based on dimension reduction is proposed. 2 kinds of adaptive 3D beamforming algorithms can dynamically adjust the weights of array elements.The pattern of antenna array is changed adaptively to provide real-time tracking service for users.Simulation results show that both algorithms can realize adaptive three-dimensional beamforming for desired users under the condition of a certain number of array antenna elements.
