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...
很多不同的厂家生产各种型号的计算机,它们运行完全不同的操作系统,但TCP.IP协议族允许它们互相进行通信。这一点很让人感到吃惊,因为它的作用已远远超出了起初的设想。T C P / I P起源于6 0年代末美国政府资助的一个分组交换网络研究项目,到9 0年代已发展成为计算机之间最常应用的组网形式。...
