Performance of 5GNR with Interference Alignment

摘要

Recently, a New Radio (NR) structure has been proposed for fifth generation (5G) mobile radio systems to support higher data rates and low latency scenarios. In this paper, we investigate the performance of 5G New Radio (5GNR) using precoding for Interference Alignment (IA). The system is based on an OFDM structure following the NR scheme with zero forcing receiver. It is shown that with proper selection of the precoder, an improvement of about one order of magnitude in the bit error rate due to IA is achieved.
