多进制数字相位调制(MPSK)系统
Abstract
Multiple Phase Shift Keying (MPSK - multiple phase shift keying) is also called multi-phase system, which is the promotion of the two-phase system. It is the modulation to characterize digital information using the different carrier’s phase state. Similar with the Binary Digital Phase Modulation, it has the absolute phase modulation (MPSK) and phase modulation (MDPSK) as the two kinds of modulation methods.
This article is mainly about the Multiple Phase Shift Keying system (MPSK) based on Xilinx ISE simulation software design, setting 4PSK as an example. The modulation method is the simple phase-selection method. It only concentrates on the design of digital system, neglecting the analog circuit system.

摘要
多进制数字相位调制(MPSK - multiple phase shift keying)又称多相制,是二相制的推广。它是利用载波的多种不同相位状态来表征数字信息的调制方式。与二进制数字相位调制相同,多进制数字相位调制也有绝对相位调制(MPSK)和相对相位调制(MDPSK)两种。
本文主要研究基于Xilinx ISE仿真软件设计的多进制数字相位调制
(MPSK)系统,以4PSK系统为例。调制方法采用简便的相位选择法,且略去模拟电路系统部分,仅对数字系统进行设计。
