The ISI is bound to appear in digital communication, and the elimination of the ISI is very important to the improvement of communication quality. This paper introduces the constitution and working principle of the adaptable equalization in communication transmission systems, and analyzes its transmission effects with the simulation software MATLAB. The simulation results show that the ISI can be eliminated effectively with adaptable equalizers in baseband transmission, and the digital communication system takes on favorable transmission characters .
