A method and apparatus for receiving a communication signal r(t) subject to noise n(t) over a communication channel ( 10 ) is disclosed. The method comprises the steps of: receiving ( 100 ) the communication signal r(t) comprising the noise n(t), estimating ( 103 ) the amount of noise n(t) in the communication signal r(t), and determining ( 105 ) the hue of the estimated amount noise n(t), wherein the received communication signal r(t) is passed through a whitening filter if the hue of the noise n(t) is greater than a predetermined threshold level. |
