Implementation and Verification of LTE-V2X Algorithm Based on Software Radio Platform

C-V2X has become one of the mainstream technologies of vehicle-to-everything (V2X) communications, which can provide low delay and high-reliability communication. However, the domestic standards related to LTE-V2X are still in the early stage, and to promote the development process, this paper presents in detail the implementation and verification of the LTE-V2X algorithm based on software radio platform. The key technologies of LTE-V2X were analyzed and studied, and the testing work was carried out in the laboratory to complete the symbolic synchronization and physical layer receiving process, and the functionality of the platform was verified.
