摘要
本文论论广播电视系统中多路数字伴音信道的设计问题。给出了系统参数与输出信号眼图开启度之间的关系式。在接收端采用简化滤波器的条件下,对全信道进行优化设计。以确定发送瑞复杂的成形滤波器最佳参数,保证输出信号眼图开启度最大,从而有效地消除接收滤波器带来的符号间干扰。本文还给出了数字实例。
This paper discusses the design question about the digital multiplexed sound channel in television broadcasting sysytems. The relationship between the system parameters and the eye pattern opening of the output signal is given. When a simple filter in the receiver is uscd, the overall channel is optimized. Optimal parameters of the complex shaping filter in the transmitter are determined, in order that the maximum eye pattern opening of the output signal is obtained. Tire intersymbol interference caused by ...
