摘　　要：在对2.4 GHz技术研究的基础上,针对无线传感器网络应用设计了一种半双工无线数传模块。该模块应用Cypress Wireless USB硬件平台,以通用MCU为处理器,结构简单。软件设计在充分应用射频芯片既有功能的基础上,增加纠错编译码、频率捷变等功能,提高了系统可靠性。对该模块完成了工程实现,实验证明该模块达到预期指标。Based on the research of communication technology at 2.4 GHz frequency spectrum, half-duplex wireless data- transmission module is designed according to the wireless sensor net-work application. Cypress wireless USB hard ware platform and MUC processor is applied in the module, with the priority of easy construction. Except for full application of the existing function of the RF CMOS chip, the function of BCH code and decode, frequency agility and so on is enhanced in order to improve the sys- tem reliability. Project realization is also completed in this paper, which is tested to achieve the expected indexes.
