【摘要】:在車聯(lián)網(wǎng)環(huán)境下對打車軟件通信系統(tǒng)進行優(yōu)化設(shè)計,改善用戶體驗,提高通信實時性和吞吐性能。提出一種基于通信信號收發(fā)轉(zhuǎn)換動態(tài)增益控制的車聯(lián)網(wǎng)環(huán)境下打車軟件通信系統(tǒng)優(yōu)化設(shè)計方法。首先進行通信系統(tǒng)的總體設(shè)計構(gòu)架和模塊化集成設(shè)計的功能分析,針對車聯(lián)網(wǎng)通信信道受到的碼間干擾較強的問題,采用動態(tài)增益編碼方法進行碼間干擾控制,進行信道均衡設(shè)計;然后對打車軟件通信系統(tǒng)進行硬件電路設(shè)計;最后進行系統(tǒng)的調(diào)試分析。實驗表明,采用該系統(tǒng)進行車聯(lián)網(wǎng)打車軟件通信的傳輸時延較低、吞吐量較大。
[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.
