【摘要】 微功率无线通信系统以其低功耗、低成本、组网简单等优势,被广泛应用在工业和民用领域。但同时它也存在着易受干扰和通信距离太近等不足。为了提高微功率无线通信系统的性能,本文研究了BCH编译码理论,论述了一种快速BCH编译码算法和交织技术的软件实现方法。完成了基于PTR8000无线数传模块和AVR单片机的无线通信系统的硬件设计以及各功能模块的调试,实现了点对点的无线通信。进一步研究了按接力方式传输的点对点的多跳型无线网络。最后完成了对整个系统通信性能的测试。更多还原

【Abstract】 Micro power wireless communication system with the advantages of low consumption, low cost and forming network simply, has been widely applied to industry and civil field. But at the same time it has the disadvantages of easily be interfered and too short distance of communication.In order to improve the performance of the micro power wireless communication system, this text has studied BCH coding/decoding theory, expound a fast BCH coding/decoding algorithm, interleaving technology and their software implementation. The hardware circuit design and debugging of the radio system based on PTR8000 module and AVR is completed. Point-to-point wireless communication has been carried out. Further more this text studies the point-to-point jumping type wireless network according to relay way. In the end the test to the whole communication performance of the system is completed.更多还原
