| 摘 要： | 针对强不相关变化算法不适用于谱系数相同的非圆信号的问题,提出了一种自适应复数独立分量分析算法.利用非圆信号的二阶统计量都不为零的特点构造代价函数,在复数域中直接优化代价函数,推导出一种针对非圆信号的自适应算法.该算法不仅对谱系数相同的非圆信号有效,而且适用于任意包含有非圆信号的统计独立的信源信号,不需要计算特征向量和奇异向量,算法的结构简单.实验仿真结果验证了算法的有效性. |

| Abstract: | To overcome the strong uncorrelated transform algorithm's inapplicability to noncircular signals with the same spectral coefficients,an adaptive algorithm with independent component analysis(ICA) for complex valued signals was proposed.A cost function was constructed for this algorithm based on the property that second order statistics of noncircular signals were not zero.By optimizing the cost function directly with a complex valued gradient,an adaptive algorithm for noncircular signals was derived.This al... |
