Patent

CA 2177625

A dynamically regularized fast recursive least squares (DR-FRLS) adaptive filter and method are disclosed which provide ?(N) computational complexity and which have dynamically adjusted regularization in real-time without requiring restarting the adaptive filtering. The adaptive filter includes a memory for storing at least one program, including a dynamically regularized fast recursive least squares (DR-FRLS) program; and a processor which responds to the DR-FRLS program for adaptively filtering an input signal and for generating an output signal associated with the input signal.
