【摘要】:针对毫米波相阵架构提出了一种迭代波束成形方法.该方法利用在阵列较大的情况下,毫米波信道不同路径的近似正交的性质,通过在收发端阵列不断对信号进行迭代发送和接收,从而获取毫米波信道中具有最大增益的路径,并以最大增益路径对应的阵列响应作为收发双方的波束成形向量.仿真表明,该方法能够获得接近于奇异值分解方法的频谱效率,实现高速率数据传输;同时具有快速收敛的特性,一般在迭代3次后算法收敛.
[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.
