摘　　要：针对无线广播接收信号的质量低、频点不稳定、容易受到电磁干扰等问题,提出了一种通过软件设计来解决或改善该问题的方案。文中的三波段广播接收机采用STM32为主控芯片,SI4735为无线广播接收芯片,在功能上通过软件设计实现了对FM、AM、SW三个波段信号的接收,同时在PC端可以实现设置三波段某一频率的广播接收,以及读取当前频率性能参数信息的功能。实验测试结果表明,三波段广播接收机性能稳定、信号优良、抗干扰性能强,验证了软件设计方案的有效性,具有很好的实际使用价值。Aiming at the problems of low quality,unstable frequency and electromagnetic interference,proposes a software design scheme to solve or improve the problems. The three-band radio receiver to STM32 as main control chip,SI4735 for wireless radio receiver chip,through the software design on the function of FM,AM,SW three band frequency receiving,at the same time in the PC can realize three band a radio frequency receiving set,the function of the information and read the current frequency performance parameters.The experimental results show that the three-band broadcast receiver has stable performance,excellent signal and strong anti-interference,which verifies the validity of the software design and has a good practical value.
