摘要
针对通信系统中基带调制的多模式的需求,基于软件无线电原理,用FPGA设计了一种可实现2ASK、2FSK、BPSK三种调制模块,在Quartus II环境中利用VHDL语言完成了芯片程序的设计,并对其进行了仿真和功能测试,实验结果验证了用FPGA可快速实现2ASK、2FSK和BPSK基带调制功能,调制信号稳定可靠,可以用软件来控制调制方式,系统方案正确可行,而且具有良好的稳定性和灵活性。
Signal transmission in digital communications need to change equipment to increase the function. The paper based on software radio, it focuses on using FPGA to realize 2ASK, 2FSK, BPSK modem; Completed the program design of the chip using VHDL language in the Quartus Ⅱ environment, then do simulation and functional testing. The experimental results demonstrate the feasibility and flexibility of the 2ASK, 2FSK and BPSK modulation in FPGA. The modulated signal is stable and reliahle, and the modulation mode can use the software to control, system scheme is correct and reliable.
