However, these receivers assume implicitly or explicitly circular (or proper) interferences and become suboptimal for noncircular (or improper) interferences.
However, most of the available receivers assume a second order (SO) circular (or proper) total noise and become suboptimal in the presence of SO noncircular (or improper) interferences, potentially present in the previous applications.
Nevertheless, all the previous detectors assume implicitly or explicitly a second order (SO) circular [10] (or proper [11]) total noise and become suboptimal in the presence of SO noncircular (or improper [12]) interferences, which may be potentially present in radio communications, localization and radar contexts.

While this is the optimal strategy when dealing with proper complex random processes [11], it turns out to be sub-optimal in situations where the transmitted signals and/or interference are improper complex random processes, for which the pseudo-autocorrelation function is non-vanishing, and the performance of a linear receiver can be improved by the use of widely linear processing (WLP) [12].
