报告摘要：Recent advances in the augmented complexstatistics show that the covariance matrix cannot completely describe the second order behavior ofgeneral complex-valued signals, and another second ordermoment, called the complementary covariance matrix, should also be taken into account, especially when processing second order noncircular (improper)data. Intuitively speaking, this is achieved by using thewidely linear estimation model. This talk will introduce widely linear adaptive filters forthe estimation of improper complex-valued inputs, as well as their full secondorder performance analysis. Widely linear adaptive frequency estimation and unbalancedvoltage detection for power systems will also be discussed.
