Abstract:
Various embodiments to provide cancellation techniques that can be used to address the self-quieter problem are described. For example, a receiver that includes a tone selector and a self-quieter suppressor is provided. The tone selector (202) determines and selects a self-quieter corrupted tone from a frequency domain signal that exhibits a self-quieter. The self-quieter suppressor (203) determines an initial phase, an angular speed and an amplitude estimate for the frequency domain self-quieter. The suppressor then generates a reconstructed frequency domain self-quieter using the initial phase, the angular speed and the amplitude estimate and subtracts the reconstructed frequency domain self-quieter from the corrupted tone to produce a self-quieter suppressed tone to replace the corrupted tone. Such an approach can realize a significant reduction in processing and complexity, as compared to known alternatives, making it an attractive and cost-effective solution for dealing with the self-quieter problem.
