Abstract: A method for impulsive noise mitigation using an adaptive blanker based on BPSK modulation system includes estimating narrowband Middleton parameters of impulsive noise from signals received for a fixed time period; calculating a threshold using the estimated narrowband Middleton parameters; operating the first blanker to suppress impulsive noise from the signal received at a given point of time through the comparison of the SNR value of the received signal and the threshold. Further, the method includes operating the second blanker to suppress impulsive noise from the received signal through the comparison of the summation of the threshold and the SNR value with an absolute value of the received signal, when the SNR value is above the threshold.
