Testing Method Discussion of FM Simulcast System

Abstract

This paper introduces the development of FM simulcast, as well as the specific implementation methods and requirements of FM simulcast system for "Triple Same" and "One Guarantee". Finally, this paper takes the same frequency overlay network of JingJinTang highway as example, furthermore, details the FM simulcast system how to accomplish the testing of the same frequency, the same modulation, the same phase and cover the field strength.
