在可编程的FPGA上能够做些什么?作者向您介绍了他的跳频频谱扩展发射机的数字逻辑类项目。软件无线电正在推动着通信领域的变化。软件无线电使用软件技术实现如调制,解调和滤波等数字处理领域的所有功能。相对于传统的模拟无线电架构,这样做的好处是软件无线电允许采用更少的元件构建系统,同时也使得即使在系统建立以后也具有更大的灵活性。有几种常见的方法实 What can I do with a programmable FPGA? The author introduces you to the digital logic project of his frequency hopping spectrum spreading transmitter. Software radio is driving changes in the communications arena. Software radios use software technology to perform all functions in digital processing such as modulation, demodulation and filtering. The benefit of doing so over traditional analog radio architectures is that software radios allow for system building with fewer components while also providing greater flexibility even after the system is set up. There are several common ways to do this
