Abstract :
This article presents a method to blindly identify linear quadratic channels (LQC). The method is designed for the single-input/single-output (SISO) case with white inputs with specific distributions (such as those usually found in digital communications). Using high-order statistics (HOS) of the input, the method is able to match the third-order moments with the LQC model, yielding an original simple relation. Several simulations are performed and show a fair accuracy given sufficiently long observation records
