数字调制解调技术在数字通信系统占有非常重要得地位，当今FPGA已成为电子设计应用市场上首选的可编程逻辑器件之一；各个领域无处不见FPGA得身影。随着电子工艺得进步，FPGA器件本身的性能逐年在提高；使得FPGA器件与其他器件相比更具有竞争力；数字通信技术与FPGA的结合是现代通信系统发展的一个必然趋势。
VHDL是一种描述数字电子系统得语言，它源自美国政府的甚高速集成电路（VHSIC）计划。VHDL语言能满足设计过程中的各种需要；本文中用VHDL进行FPGA的调制与解调系统的设计。
本文介绍了ASK、FSK、QPSK调制与解调得原理；并基于FPGA实现ASK、FSK、QPSK调制与解调电路。用VHDL语言编程分别实现ASK、FSK、QPSK调制与解调；并用Altera公司推出的完全集成设计环境QuartusII进行编译仿真；进而证明此设计的正确性。
VHDL语言具有功能强大的语言结构；可读性强，易于修改和发现错误；可移植性强；成本低；设计与工艺无关；ASIC移植；可使用仿真器对VHDL源代码进行功能仿真；但对于初学者容易犯错，算法需要不断调试仿真加以认证。

Digital modulation and demodulation techniques in a digital communication system has a very important position, FPGA has become today's electronic design applications market preferred one of the programmable logic device; not all fields FPGA nowhere in the scene. With advances in electronic technology, FPGA performance of the year in improving; making FPGA devices compared with other more competitive; digital communication technology and FPGA combination of modern communication systems development a natural trend. VHDL is a description of digital electronic systems in the language, It originated from the United States government's very high-speed integrated circuit (VHSIC) program. VHDL design process to meet the various needs; In this paper, using VHDL for FPGA modulation and demodulation system design. This paper introduces the ASK, FSK, QPSK modulation and demodulation in principle; Based on FPGA ASK, FSK, QPSK modulation and demodulation circuit. Us
