video
- 分辨率这个词其实用得很广泛，摄像头有分辨率、照相机有分辨率、显示器有分辨率、显微镜也有分辨率，同样，广播电视、数字视频也有分辨率，各个不同的领域对分辨率有着不同的定义，即使同一个领域，对于同一种分辨率的定义也会根据制式的不同而有所不同，例如D1分辨率，到底是720x480还是720x576呢？刚刚开始接触视频采集的人或许会有着很多的困惑，那么，本文就是专注于讲述与广播电视与数字视频相关的分辨率分类。-Term resolution of this fact, very widely, camer
CS8955_RDS
- RDS(Radio Data System)数据广播系统是将数字信号调制到调频波段 (87.5~108MHz)并以广播的形式发送的一种信号传输系统。这种传输模式在北美 和欧洲得到了采用，而且得到越来越多的其他国家的关注。在北美和欧洲 都有 相应的标准，即RBDS 和RDS。 传输数据时，数据加载到57KHz 的副载波频段。副载波经过调制以适应固定 的双相编码信号。这个副载波经过抑制以避免调制后的数据在锁相环立体声解码 器中产生混叠同时还要与德国同样采用57KHz 频率作为
qpsk_demod_use_FPGA
- 根据软件无线电的思想，提出了一种新颖的数字信号处理算法，对QPSK信号的相位进行数字化处理，从而实现对QPSK信号的解调.该算法允许收发两端载波存在频差，用数字锁相实现收发端载波的同步，在频偏较大的情况下，估算频偏的大小，自适应设置环路的带宽，实现较短的捕获时间和较好的信噪性能。整个设计基于XILINX公司的ISE开发平台，并用Virtex-II系列FPGA实现。用FPGA实现调制解调器具有体积小、功耗低、集成度高、可软件升级、扰干扰能力强的特点，符合未来通信技术发展的方向。-According
