The ’WP010 is a ROM-coded DSP that provides all the adaptive filtering and processing necessary for acoustic echo cancellation (AEC), line echo cancellation (LEC), and adaptive noise suppression (ANS).
The ’WP010’s acoustic echo cancellation function is based on a Finite Impulse Response (FIR) filter with an adaptive coefficient updating algorithm.
The adaptive algorithm updates continuously so that it can constantly track acoustic path changes from the speaker to the microphone.
Based upon FIR filter coefficients, the echo signal can be estimated and subtracted from the observed signal at the microphone.
The acoustic echo cancellation function provides continuous adap...
