学术论文 DVBT信道编解码算法研究及FPGA实现

数字通信系统中,在实际信道上传输数字信号时,由于信道传输特性不理想及噪声的影响,接收端所收到的数字信号不可避免地会发生错误。为了减小误码率,提高接收质量,必须采用差错控制编码。对于数字视频通信系统这类高码率,高要求的系统,为了提供优良的图象质量,采用差错控制编码尤为重要。 本文采用的DVB-T系统差错控制 ...

PCB相关 用单层PCB设计超低成本混合调谐器

今天,电视机与视讯转换盒应用中的大多数调谐器采用的都是传统单变换MOPLL概念。这种调谐器既能处理模拟电视讯号也能处理数字电视讯号,或是同时处理这两种电视讯号(即所谓的混合调谐器)。在设计这种调谐器时需考虑的关键因素包括低成本、低功耗、小尺寸以及对外部组件的选择。本文将介绍如何用英飞凌的MOPLL调谐芯片TUA603 ...
