Research On Interference Cancellation And Its Application In V2V Communication

In recent years, Internet of Vehicles and V2V are developing at a very rapid rate. V2V is one of emerging research direction worthy of extensive research for advanced communications technology researchers.It contains quite a number of new directions worthy of further optimization,which needs more scholars to open up.In the traditional V2V process, we will receive the information in addition to the information of highest power, and the information sent by other nodes is regarded as interference. We can only detect the information of highest power, and the information sent by other nodes can not be timely accessed. There may be unintended consequences, so if the receiving node can detect the information sent by other nodes and can control the error rate in a relatively low range, it can greatly improve the plant communication quality and increase the transmission content. The main work and achievements of this paper are as follows:By using the WAVE ( Wireless Access in Vehicular Environments )scheme of DSRC ( Dedicated Short Range Communications ) in the V2V technology, the communication model is established and the packet wake-up scheme is designed by RFID ( Radio Frequency IDentification )radio frequency signals. The number of packets transmitted is controlled at each time. In addition, the beam forming technology is introduced into the workshop communication application of serial interference cancellation algorithm. And the information's sending and receiving is controlled in the same lane, so that the amount of information is increased,and the accuracy of information is increased. Thus, the received signal is processed by serial interference cancellation algorithm. Then, the signals are compared with the transmitted signals to obtain a series of curves which affect the communication performance indexes of the V2V. The results are compared with the traditional anti-collision algorithms, and the results are related to the communication performance of the V2V. Finally,the conclusion is obtained by the analysis.
