We present a real-time implementation of a new fast LMS-based algorithm, which was shown in earlier work to supersede the LMS algorithm in its rate of convergence with little misadjustment. Our implementation employs the new algorithm in echo cancellation in a telephone network with the TMS32020 processor. The implementation shows the advantage of the new algorithm over the conventional LMS in achieving faster convergence with less misadjustment, due to the larger bound allowed on the step size, /spl mu/, derived for the algorithm. This result is demonstrated in simulating the operation of the echo canceller using actual noisy speech signals.< >
