5G Toolbox™ provides standard-compliant functions and reference examples for the modeling, simulation, and verification of 5G New Radio (NR) communications systems. The toolbox supports link-level simulation, golden reference verification, conformance testing, and test waveform generation.
With the toolbox you can configure, simulate, measure, and analyze end-to-end 5G NR communications links. You can modify or customize the toolbox functions and use them as reference models for implementing 5G systems and devices.
The toolbox provides functions and reference examples to help you characterize uplink and downlink baseband specifications and simulate the effects of RF designs and interference sources on system performance. You can generate waveforms and customize test benches, either programmatically or interactively using the Wireless Waveform Generator app. With these waveforms, you can verify that your designs, prototypes, and implementations comply with the 3GPP 5G NR specifications.
Get Started:
NR Subcarrier and Numerology
Generate 5G NR uplink and downlink carrier waveforms based on flexible NR subcarrier spacings and frame numerologies, including carrier bandwidth parts (CBP).
Downlink carrier waveform generation.
Wireless Waveform Generation App
Generate 5G NR test models (NR-TM) and NR uplink and downlink fixed reference channel (FRC) waveforms. Add RF impairments such as AWGN, phase offset, frequency offset, DC offset, IQ imbalance, and memoryless cubic nonlinearity. Visualize in constellation diagram, spectrum analyzer, OFDM grid, and time scope plots.
Test model generation using Wireless Waveform Generator App.
Propagation Channel Models
Perform block error rate (BLER) simulations with TR 38.901 propagation channel models. Characterize and simulate cluster delay line (CDL) and tapped delay line (TDL) channel models.
TDL channel model path gains.
Throughput Testing
Characterize 5G NR link-level performance and measure physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) throughputs.
NR PDSCH throughput.
Signal Reception
Perform channel estimation and equalization on received 5G NR signals.
5G NR channel estimations.
RF Modeling and Testing
Evaluate the performance of 5G RF transmitters. Model and test NR RF receivers in the presence of interference.

Control Information
Simulate uplink and downlink (UCI, DCI) control information and control resource sets (CORESETs).
Downlink control processing.
Transport Channels
Use low-density parity-check (LDPC) coding to encode and decode transport channels, including uplink and downlink shared channels (UL-SCH and DL-SCH).
5G NR polar coding.
Synchronization
Construct a waveform containing a synchronization signal (SS) burst, pass waveforms through a fading channel, and blindly synchronize to receive the waveforms.
NR synchronization procedures.
Selection Procedures and MIB Decoding
Decode the Master Information Block (MIB). Model the physical random access channel (PRACH) missed detection conformance test.
BCH decoding and MIB parsing.
Scheduling
Evaluate the performance of medium access control (MAC) scheduling strategies in both time division duplexing (TDD) and frequency division duplexing (FDD) modes.
NR PUSCH MAC scheduling.
Open MATLAB Code
Use transmitter, channel model, and receiver operations that are expressed as open and customizable MATLAB® code.
