【摘要】:在车联网环境下对打车软件通信系统进行优化设计,改善用户体验,提高通信实时性和吞吐性能。提出一种基于通信信号收发转换动态增益控制的车联网环境下打车软件通信系统优化设计方法。首先进行通信系统的总体设计构架和模块化集成设计的功能分析,针对车联网通信信道受到的码间干扰较强的问题,采用动态增益编码方法进行码间干扰控制,进行信道均衡设计;然后对打车软件通信系统进行硬件电路设计;最后进行系统的调试分析。实验表明,采用该系统进行车联网打车软件通信的传输时延较低、吞吐量较大。
[Abstract]:The software communication system is optimized to improve the user experience in the environment of car networking. This paper presents a method for optimizing the design of the cab-hailing software communication system based on the dynamic gain control of the communication signal transceiver conversion. Firstly, the overall design framework of the communication system is carried out. And function analysis of modular integrated design. Aiming at the problem of strong inter-symbol interference (ISI) in vehicle network communication channel, the dynamic gain coding method is used to control the inter-symbol interference (ISI) and the channel equalization is designed. Then the hardware circuit of the system is designed. Finally, the system is debugged and analyzed. The experimental results show that the transmission delay and throughput of the system are lower and larger.
