摘　　要：随着科学技术的发展和进步,广播电视卫星信号在日常生产生活中的应用更加广泛,因此,其信号的稳定性显得尤为重要。传统的广播电视卫星信号使用的数字调制解调器技术已经无法满足现阶段的实际需求,随之也研究出了诸多全新的数字调制解调技术。有关部门应针对新数字调制解调器组织开展相应的研究工作,根据不同情况选择不同的数字调制解调技术,满足社会发展过程中的实际需求。With the development and progress of science and technology, radio and television satellite signals are more widely used in daily production and life. Therefore, the stability of their signals is particularly important. The traditional digital modem technology used for radio and television satellite signals can not meet the actual needs at this stage, so many new digital modulation and demodulation technologies have been developed. Relevant departments should organize and carry out corresponding research work on new digital modems, select different digital modulation and demodulation technologies according to different situations, and meet the actual needs in the process of social development.
