摘要
为了提高数字多媒体广播(DMB)系统的灵敏度与可靠性,通过长时间统计分析数字多媒体广播系统在重庆邮电大学等学校运行时的各种参数,建立可靠性基本评估模型;同时研究数字多媒体接收终端,主要通过研究滤波器设计、阻抗匹配、共地干扰等方面,使数字多媒体广播系统的灵敏度有所提高。
In order to improve the sensitivity and the reliability of the digital multimedia broadcasting （DMB） system, it is a long statistical analysis that thevarious parameters of the digital multimedia broadcasting systems at runtime inChongqing university of posts and telecommunicationsto establish the model realiable.At the same time, the method of Digital Multimedia Terminal is the filter design, impedance matching, a total of interference and so on, so that the sensitivity of the digital multimedia broadcasting system could be improved.
