【摘要】：針對毫米波相陣架構提出了一種迭代波束成形方法.該方法利用在陣列較大的情況下,毫米波信道不同路徑的近似正交的性質,通過在收發(fā)端陣列不斷對信號進行迭代發(fā)送和接收,從而獲取毫米波信道中具有最大增益的路徑,并以最大增益路徑對應的陣列響應作為收發(fā)雙方的波束成形向量.仿真表明,該方法能夠獲得接近于奇異值分解方法的頻譜效率,實現(xiàn)高速率數(shù)據(jù)傳輸;同時具有快速收斂的特性,一般在迭代3次后算法收斂.
[Abstract]:An iterative beamforming method is proposed for millimeter wave phased array architecture. This method utilizes the approximately orthogonal property of different paths of millimeter-wave channel in the case of large array, and obtains the path with maximum gain in millimeter-wave channel by iterating over and receiving signals from the array at the transceiver end. The array response corresponding to the maximum gain path is used as the beamforming vector of both the transceiver and receiver. Simulation results show that the proposed method can obtain the spectral efficiency close to that of the singular value decomposition method and achieve high rate data transmission. At the same time, it has the property of fast convergence, which generally converges after three iterations.
