基于协议优化的微功率无线通信的抗干扰设计

Design of Preventing Interference for Low Power Wireless Communication Based on Protocol Optimized

微功率近距无线通信因其工作在ISM频道无需申请频点而获得了广泛的应用,但由此而来的干扰常常使其无法正常工作。针对这一困惑,提出了一个在不增大发射功率和不改变通信频道的前提下设法有针对性的优化编解码协议的解决方案,并以ET13X210/221无线模块作为应用实例讨论了这一方法的具体实现。

Low-power short-range wireless communication has been used in many fields because of running in the ISM frequency band and without any requisition of new license. But in such public frequenCy band the more application come into μ s e, the more interference will appear. In order to prevent such interference a scheme was presented which optimizes the protocol of encode and decode without switching to other channels or increasing the transmission power. It was disc μs sed with ET13X210/221 transceive module to show the details.
