IMPULSIVE NOISE IN DIGITAL-COMMUNICATION

Digital signalling is the preferred form of signalling because of its well known and now easily realizable merits. The techniques for digita l communication in continuous noise are well engineered. Serious probl ems arise when noise is impulsive. This form of noise severely degrade s the system performance and calls for more complicated types of noise reduction techniques, optimum receiver and error control coding. This paper briefly presents the work carried out in this area by the autho rs and emphasizes the role that the impulsive noise plays in the desig n of digital communication systems.
