A method of detecting an impulse noise component for a data transmission signal in a mobile environment includes receiving over a communication channel a demodulated signal having an input signal level subject to a fading condition where the input signal level varies without the presence of the impulse noise component; estimating a variation of the input signal level independently of the impulse noise component under the fading condition to obtain a robust signal level estimate of the signal; and detecting the impulse noise component based on the robust signal level estimate and the input signal level. The method also includes reducing the impulse noise component by cancelling a signal component of the received signal whose impulse noise component has been detected.
