摘 要: 基于相位键控的一些基本方法运用的正交查分相移相关知识研究π/4QDPSK编码解码技术。并且根据π/4QDPSK编码解码技术原理运用SystemView软件实现硬件上的仿真,说明π/4QDPSK编码解码技术在现实生活中的信道传输里是可实现的。 The coding and decoding technology of π/4 QDPSK is studied. Based on some basic knowledge of how to control signal by phase-shift, and based on the knowledge of latus rectum signal controlled by π/4 phase-shift. Then, making this technology comes true in hardware by using SystemView to improve the realization of it.
