Parameter estimation of coexisted circular and strictly noncircular signals

What is it about?

This publication proposes a noval parameter estimation (DOA and noncircular phase) of coexisted circular and noncircular signals algorithm in a fast (polynomial rooting) method instead of spectral searching, which can be applied to arbitrary planar array configurations.

Why is it important?

The coexistence of circular and noncircualr signals has attracted the attention of relevant experts recently. This publication supplies a new perspective about the problem, and fills the gap in the area the fast parameter estimation (DOA and noncicular phase) of coexisted circular and noncircular signals for arbitrary planar array.
