Database supported successive interference cancellation scheme for intra-platoon communications

High reliability of wireless communications is a rudimentary requirement for guaranteeing safe autonomous driving. This paper discusses the performance of communications between cars within autonomous platoons, with the application of a proposed database-supported successive interference cancellation (SIC) algorithm. By assumption, it utilizes the knowledge on other existing interfering transmissions (such as pre-entered information on digital television transmissions stored in the roadside database) to remove the interfering signal at the receiver side. It is shown that this approach improves the bit error rate, and in turn — the reliability of intra-platoon transmission. The proposed solution is evaluated using link-level extensive computer simulations.
