摘要
 
 相移鍵控（PSK）是在太空計(jì)劃的早期發(fā)展起來的，廣泛應(yīng)用于軍事和商用的通信系統(tǒng)中。BPSK調(diào)制便是其中被廣泛應(yīng)用的數(shù)字調(diào)制方式之一。
 本論文介紹了數(shù)字通信中的BPSK調(diào)制原理，仿真分析了四種基帶信號的調(diào)制，利用CPLD芯片進(jìn)行BPSK調(diào)制器研究設(shè)計(jì)。在軟件設(shè)計(jì)中，盡可能采用模塊化編程，以逐步完善系統(tǒng)結(jié)構(gòu)；在硬件設(shè)計(jì)過程中，盡可能采用已經(jīng)成熟的經(jīng)典電路，并進(jìn)行了部分改進(jìn)。
 本文研究的數(shù)字調(diào)制方法適應(yīng)當(dāng)前科學(xué)技術(shù)的發(fā)展與更新，具有一定的實(shí)用價(jià)值。本設(shè)計(jì)開發(fā)的CPLD實(shí)驗(yàn)板可以為學(xué)生創(chuàng)新性實(shí)驗(yàn)提供平臺。

ABSTRACT
 
 PSK was developed in the early space program and widely used in military and commercial communications systems. BPSK is one of the widely used digital modulation techniques.
 This paper introduces the principles of BPSK and presents the simulation and analysis of the modulation of four kinds of baseband signals. The design and realization of the BPSK modulator based on CPLD chip is also introduced. In the process of hardware design, it usually uses the mature classical circuits and makes some improvements; in software design, module programming and structure programming are widely used.
   The digital modulation techniques studied in this thesis adapt to the development of science and technology. The CPLD lab board designed in this paper will be used as a platform for the creative experiments in the future.

Keywords: BPSK, CPLD, VHDL
