| Abstract |
The 3rd Generation Partnership Project (3GPP) has recently developed enhanced vehicle to everything (eV2X) communication. The requirements of the eV2X service are dramatically higher than the existing V2X, with the required data transmission rates ranging from tens of Mbps to up to 1000 Mbps. In addition, the communication should be performed with a very low error probability within a time delay of several to several tens of ms. In this paper, low-density parity-check (LDPC) code and 256 QAM of new radio (NR) technology 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 (MIMO) system that improves reliability through transmit diversity and reduces latency through short transmission time interval (sTTI). Simulation results show that the proposed system has high reliability, data rate and short latency. |
