A linear/non-linear adaptive filter for transforming an input signal to an output signal. The present invention also includes a novel GSPT LMS algorithm for significantly reducing complexity. The adaptive filter includes a coefficient updater that can execute a Carry-in operation or a Borrow-in operation...http://www.google.com/patents/US20040114544?utm_source=gb-gplus-sharePatent US20040114544 - Adaptive filter with GSPT LMS algorithm for reducing complexity
