Research of noise characteristics and multi-carrier modulation technology based on PLC communication

The communication principle of PROFIBUS Fieldbus;

Simulation experiment of communication principle by system view;

Constructing the multi-way practice teaching system for communication principle course;

Exploration and Practice in Teaching the Course of Communication Principles;

The present paper,based upon features of communication principles course,discusses ways and means to reform the course and practice experience as well in the light of teaching content,curriculum coordination,teaching method and media,practice teaching and evaluation mode so as to develop a brand-new mode in teaching the course and ensure a thorough reform in specialty teaching.

The several characteristics of the modulation techniques in the course communication principles are analyzed, and how to use the method named as four-dimensional thinking space in teaching practice is discussed.
