摘要
该文针对两个传感器三个信号源的(即M<N)盲信号分离问题,推导出了一种基于高阶累积量的复数混合矩阵盲估计算法.提出的算法当信号源的个数大于传感器的个数时,成功实现通道参数的盲估计,计算机仿真验证了算法的有效性。
Based on higher-order cumulants, the blind estimation of complex mixed matrix for the difficult case of 2 sensors and 3 sources is addressed. When the number of source signals is greater than or equal to the number of sensors, the proposed algorithm can successfully estimate the channel matrix. The performance of the algorithm is evaluated by computer simulation.
