摘　　要：QPSK(正交相移键控)广泛应用于卫星通信、移动通信等领域,它具有抗噪声能力强、频带利用率高以及易于硬件实现等优点。基于FPGA实现的QPSK调制器具有开发周期短、节省成本、可移植性好、集成度高等优势。整个系统的设计采用自顶向下的模块化设计思想以及Verilog HDL的编程语言完成。通过Modelsim仿真以及Signal Tap逻辑分析仪验证可以发现该调制器实现了预期的功能。QPSK has been widely used in satellite communications,mobile communications and other fields. It has many advantages such as strong anti-noise ability,high bandwidth efficiency and easily implemented in hardware. The modulator based on FPGA with a number of advantages such as short development cycle,saving cost,good portability and high integration. The design of the whole system is accomplished by using the idea of top-down modularization design and the Verilog HDL programming language. Through Modalism simulation and verification with Signal Tap,expected function could be realized based on this modulator.
