A widely linear (WL) model was recently proposed for stereophonic acoustic echo cancellation (SAEC). In this framework, the classical two-input/two-output SAEC scheme with real random variables is recasted as a single-input/single-output system with complex random variables. The main advantage of this approach is that instead of handling two (real) output signals separately, we only handle one (complex) output signal. In general, due to their good convergence features, recursive least-squares… CONTINUE READING
