Research and Implementation of Mobile Communication System of Micro Aerial Vehicles

传统的数字通讯方式已不能充分满足微型飞行器移动通信系统低重量、低功耗、低误码率、高抗干扰性的需求,必须设计最佳的编码、译码和硬件实现方案来满足这些需求。通过分析比较非线性卷积编码比线性分组码在微型飞行器移动通信系统中所具有的优势,提出了把卷积编码以及维特比译码应用于微型飞行器信道传输中的具体方法,并通过把编码和解码程序移植到微型飞行器的处理器上,对处理器的工作性能进行优化,极大地改善了微型飞行器移动通信系统的性能。

Traditional digital communication is hard to sufficiently meet the requirement of low weight, low power consumption, low code error proportion and high anti -interference characteristic of mobile communication system of micro aerial vehicles. It is necessary to design the best methods of coding and decoding and hardware implementation to meet the requirement. The paper presents the method and algorithm to apply convolutional coding and Viterbi decoding by analyzing the advantages of convolutional code and comparing with linear grouping code. The coding and decoding programs are transplanted to the microprocessor aboard the micro aerial vehicles. The operation of the microprocessor is optimized. The performance of mobile communication system of micro aerial vehicles is greatly improved.
