摘　　要：为了丰富学生的高频实践教学,设计了基于计算机串口的无线通信平台。平台实现将数字系统设计技术、射频无线电技术和单片机控制技术有效结合。发射/接收采用锁相频率合成的方法提供载波和本振信号,频率稳定度较高。系统稳定,可靠实现了两台计算机串口无线通信,对学生实践能力培养和系统知识的掌握有明显的作用。In order to enrich the students＂ practice teaching in high frequency, wireless communication platform based on the computer serial port is designed.Digital system design technology, radio technology and single chip mi- crocomputer control technology can be effectively combined. The transmitter / receiver uses a phase-locked frequency synthesis method to provide the cartier and the vibration signal, Stable and reliable frequency. The system is stable and reliable. It can realize the serial communication of two computers. It has a significant effect on the students＂ practical ability training and system knowledge.
