摘要: |
本文研究了在阵列信号处理中使用累积量的问题,以及在相干多径环境中基于累积量的盲自适应波束形成技术。该技术能在阵列几何结构和阵列流形未知的条件下,自适应调整权系数使阵列输出的信号干扰加噪声比最大。 |

() |
Abstract: |
An investigation on the use of cumulants in array processing problems is made and an approach to cumulant-based blind adaptive beamforming for coherent signals is presented.The technique is applicable to any array configuration with unknown reponse.The weights of the beamformer are selected according to a new optimization objetive,which maximizes signal-to-interference plus noise ratio(SINR). |
