System-Level Simulation

5G NR multinode communications

5G Toolbox™ system-level simulations model multinode networks. The simulations operate across a protocol stack that includes physical (PHY), medium access control (MAC), radio link control (RLC), and application layers. 5G Toolbox enables you to model a New Radio (NR) waveform by using PHY and channel modeling features or abstracted PHY with link-to-system mapping. You can evaluate the network performance with different data traffic models, MAC scheduling strategies, and PHY algorithms. You can also analyze the effect of intercell interference, measure quantities like throughput, scheduling fairness, block error rate (BLER), and spectrum efficiency, and use visualization capabilities to explore the performance of the network. In addition, you can export protocol packets to packet capture (PCAP) and packet capture next generation (PCAPNG) files for network analysis.

To use the network simulation functionality with 5G Toolbox, install the Communications Toolbox Wireless Network Simulation Library add-on.
