Patent ID: 8238480

Claim:
A method for adaptive self-quieter suppression comprising: selecting a self-quieter corrupted tone from a frequency domain signal that exhibits a self-quieter; determining an initial phase, an angular speed and an amplitude estimate for the self-quieter in the frequency domain; determining a phase change rate over a time division duplex (TDD) frame interval; determining a current initial phase of a current TDD frame by searching a finite number of values of the initial phase; determining an intermediate phase that is a difference between the current initial phase and the phase change rate times a number of past TDD frames; applying a low-pass filter to the intermediate phase to reduce variation; determining the initial phase for the frequency domain self-quieter by summing the low-pass filtered intermediate phase and the phase change rate times the number of past TDD frames; generating a reconstructed frequency domain self-quieter using the initial phase, the angular speed and the amplitude estimate; and replacing the self-quieter corrupted tone by a self-quieter suppressed tone, wherein the self-quieter suppressed tone is the self-quieter corrupted tone minus the reconstructed frequency domain self-quieter.
