5G Toolbox provides standard-compliant functions and reference examples for the modeling, simulation, and verification of 5G and 5G-Advanced communications systems. The toolbox supports waveform generation, link-level and system-level simulations, golden reference verification, and conformance testing.
With the toolbox, you can configure, simulate, measure, and analyze 5G communications links and systems. You can modify or customize the toolbox functions and use them as reference models for implementing 5G devices. You can also explore candidate technologies for 6G communications systems.
The toolbox functions and reference examples help you to characterize uplink and downlink specifications, perform open radio access network (O-RAN) conformance tests, and simulate the effects of RF designs and interference sources on system performance. You can generate and analyze waveforms and customize test benches using the Wireless Waveform Generator and Wireless Waveform Analyzer apps. With these waveforms, you can verify that your designs, prototypes, and implementations comply with the 3GPP 5G New Radio (NR) specifications.
Waveform Generation and Analysis
Generate and analyze standard-compliant 5G NR waveforms. Use the Wireless Waveform Generator and Wireless Waveform Analyzer apps to configure, generate, and analyze custom waveforms, NR test models, and fixed reference channels.
Link-Level Simulation
Simulate 5G NR end-to-end wireless communication links. Incorporate transmitter, channel modeling, and receiver operations. Apply cluster delay line (CDL) and tapped delay line (TDL) channel models. Analyze the performance of 5G terrestrial and non-terrestrial network (NTN) links by computing block error rate and throughput metrics.
Test and Measurement
Evaluate the performance of 5G NR RF transmitters and receivers. Characterize RF link performance. Measure adjacent channel leakage ratio (ACLR) and error vector magnitude (EVM) metrics. Generate and analyze fronthaul control plane and user plane (CU-Plane) messages for O-RAN conformance tests.
MIMO and Beamforming
Use channel state information (CSI) feedback to adjust transmission parameters, including code rate, modulation, number of layers, and MIMO precoding matrix. Estimate uplink channels using sounding reference signals exploiting channel reciprocity in a time division duplex (TDD) scenario. Use CSI reference signals and select the optimal transmit beam based on reference signal received power measurements.
Propagation and Channel Models
Use CDL, TDL, NTN and high-speed train (HST) channel models in your simulations. Configure the CDL channel model with the result of ray tracing analyses. Explore channel information, including antenna element, element pattern, number of rays, angles, delays, attenuations, and cluster paths.
Cell Search Procedures
Perform cell search and selection procedures to extract initial system information, including Master Information Block (MIB) and System Information Block 1 (SIB1). Model the physical random-access channel. Use synchronization signal blocks to perform beam management procedures consisting of beam sweeping, measurement, determination, reporting, and recovery steps.
System-Level Simulation
Simulate frequency-time resource sharing among multiple UEs in a 5G NR network. Evaluate the performance of medium access control scheduling strategies in both TDD and frequency division duplexing modes.
AI for Wireless
Apply AI for wireless techniques to optimize 5G NR operations. Use an autoencoder neural network to compress downlink CSI. Train a deep Q-network (DQN) reinforcement learning agent for beam selection. Train a convolutional neural network for channel estimation.
6G Exploration Library
Use the 6G Exploration Library to model, simulate, and test candidate 6G waveforms. Explore 6G enabling technologies including AI and machine learning, RF component modelling for higher frequencies, integrated sensing and communications (ISAC), and reconfigurable intelligent surfaces (RIS).
