摘要
为掌握某型电台的数字中频信号设计及其通信原理，采用FPGA＋DSP＋ARM架构，以FPGA（XC3S1000）为核心实现中频信号的上下变频，以DSP（TMS320C6416）为核心实现基带信号的调制与解调，以ARM（$3C2410A）为核心实现程序加栽和模式控制，开发一个通用中频数字化信号处理系统，通过软件编程实现中频信号的数据通信，并对其通信、调制以及解调功能进行测试验证，实验结果表明其有效性。该系统可用于某型电台的通信测试与产品修理。
In order to master the design of digital IF signal of a certain type of radio and its communication principle, a digital signal processing platform based on FPGA ＋ DSP ＋ ARM multiprocessor is developed, which takes the Xilinx＇ s Spartan series FPGA m （xc3slooo） as the core to realize the up and down frequency con- version of IF signal, uses DSP （TMS320C6416） as the core to realize the modulation and demodulation of the baseband signal, and uses ARM（S3C2410A） as the core to implement program loading and mode control. A common IF digital signal processing platform was established, wireless communication was realized through va- rious software programming modes, and its communication, modulation and demodulation functions were tested. Simulation and experimental results verify its effectiveness. The system can be used for communication test and product repair of a certain type of radio station.
