Patent ID: 7010118

Claim:
A system for noise compensation comprising: a near-end noise level estimator receiving a near-end signal and generating a near-end noise level estimate based on the near-end signal; and a first noise adaptive compander comprising: a first input for receiving a far-end signal; a second input for receiving the near-end noise level estimate; a first output for producing a near-end noise compensated output signal; and a noise adaptive gain controller for generating a noise adaptive gain G N that is a function of the near-end noise level estimate and a noise sensitivity coefficient, the noise sensitivity coefficient is set to a variable value to account for variability in the near-end noise level estimate resulting from imprecise measurement of the near-end noise, whereby the first noise adaptive compander receiving the far-end signal at the first input and receiving the near-end noise level estimate at the second input, the first noise-adaptive compander operating to adjustably amplify the far-end signal based upon the noise adaptive gain G N to produce the near-end noise compensated output signal at the first output.
