无线通信 UHF读写器设计中的FM0解码技术
 
 针对UHF读写器设计中，在符合EPC Gen2标准的情况下，对标签返回的高速数据进行正确解码以达到正确读取标签的要求，提出了一种新的在ARM平台下采用边沿捕获统计定时器数判断数据的方法，并对FM0编码进行解码。与传统的使用定时器定时采样高低电平的FM0解码方法相比，该解码方法可以减少定时器定时误差累积的影 ...
可编程逻辑 基于CPLD的QDPSK调制解调电路设计
为了在CDMA系统中更好地应用QDPSK数字调制方式，在分析四相相对移相（QDPSK)信号调制解调原理的基础上，设计了一种QDPSK调制解调电路，它包括串并转换、差分编码、四相载波产生和选相、相干解调、差分译码和并串转换电路。在MAX+PLUSⅡ软件平台上，进行了编译和波形仿真。综合后下载到复杂可编程逻辑器件EPM7128SLC84-15中 ...
