Abstract:
The 3rd Generation Partnership Project (3GPP) has recently developed enhanced vehicle-to-everything (eV2X) communication. The requirements of the eV2X service are significantly higher than those of existing V2X, with the required data transmission rates ranging from tens of Mbps to up to 1000 Mbps. In addition, communication should be performed with an extremely low error probability within a time delay of several to several tens of ms. In this study, a low-density parity-check code and 256 quadrature amplitude modulation (QAM), which are new radio technologies, are applied to meet the low-latency, high-reliability, and high-data-rate requirements of eV2X. In addition, we propose a vehicle multiple-input multiple-output system. The proposed system increases reliability through transmit diversity and lowers latency through a short transmission time interval. Simulation results show that the proposed system exhibits high reliability, high data rate, and low latency.
