Abstract

A widely linear affine projection algorithm (WL-APA) utilising the full second order statistical information in the complex domain Copf is proposed. It is based on recent developments in augmented complex statistics, CopfRopf calculus, and the widely linear modelling in Copf, making it suitable for the processing of noncircular complex valued signals. Simulations on circular and noncircular benchmark and real-world noncircular wind signals show the effectiveness of WL-APA as compared to standard APA.
