摘要: 該文給出了發(fā)射陣列的誤差模型和相應的預失真校正方法。根據(jù)發(fā)射陣列的特點，提出了基于單元方向圖法和合成波束法來計算發(fā)射互耦矩陣。仿真結果驗證了這兩種方法的有效性，在有發(fā)射噪聲時第二種方法的性能要比第一種的好。Abstract: Error model and its corresponding pre-distortion calibration method for trans-mitting array are presented in this paper. According to the characteristics of transmitting array, element-pattern-based and synthesized-beam-based methods are proposed to calculate mutual coupling matrix in transmitting mode. Simulation results verify the effectiveness of present methods. The second method shows better performances than the first one for the case where the transmitting noises exist in the channels.
