A real-time subband adaptive noise cancellation system on an ultra low-power miniature DSP system is implemented. The system is targeted at personal communication devices where the speaker may be in a noisy environment. The system is implemented on an ultra low-power DSP system that incorporates a DSP core and an oversampled WOLA filterbank. Pre-emphasis filters are used to increase the convergence rate of a leaky LMS algorithm in the oversampled subband implementation. System performance is… CONTINUE READING
