Abstract
A method is disclosed for maintaining the integrity of a communication system. The method comprises detecting common path distortion (CPD) and periodic impulse/burst (PIB) noise in a received signal in the communication system. After isolating the CPD and PIB noise, ingress noise in the received signal is identified. Isolating the CPD and PIB noise thus prevents improper classification of CPD and PIB noise as ingress noise. Operating parameters of the communication system are then adapted in accordance with the identified ingress noise, the detected CPD and/or the detected PIB noise.
