Systems and methods for impulsive noise detection and mitigation

Abstract

Systems (100) and methods (200) for impulsive noise detection and mitigation are described. In particular, the system (100) includes a transmitter (102), a communication channel (106), and a receiver (104). The transmitter (102) is configured to encode an input signal, modulate the encoded signal for transmission through the communication channel (106), and transform the modulated signal into a time-domain signal. The communication channel (106) is configured to transmit the time-domain signal and a control signal from the transmitter (102) to a receiver (104). The receiver (104) is configured to transform the time-domain signal into a frequency-domain signal, detect a position of impulsive noise in the frequency-domain signal based at least on identifying a position of null subcarriers in the frequency-domain signal via the control signal, and initiate the suppression of the impulsive noise from the frequency-domain signal.
