虽然现代化的数字通信只有短短几十年的历史,但由于其保密便捷,强抗干扰性,对数字信号的处理方便,可以传输各种现有的数据,易于同光纤通信、卫星通信等新的传输手段配合等特性,因此其应用一直在不断的推广与发展。数字通信也将成为通信技术发展的一个主要方向,在现代通信技术起着不可或缺的作用。本论文设计的全数字的调制解调系统——QPSK基于最广泛的QUARTUSⅡ软件和新兴的Verilog HDL语言。
Although modern digital communications have only a few decades of history, they are easy to handle with digital signals due to their confidentiality, strong anti-interference ability, transmission of various existing data, ease of communication with optical fiber and satellite communications, etc. The transmission means with other features, so its application has been constantly promotion and development. Digital communications will also be a major direction in the development of communications technology, playing an indispensable role in modern communications technology. This paper designs the all-digital modem system - QPSK is based on the most extensive QUARTUS II software and the emerging Verilog HDL language.
