5G Toolbox


5G Toolbox

Simulate, analyze, and test 5G communications systems

Get Started:

Waveform Generation

Generate standard-compliant waveforms for the 3GPP 5G NR Release 15. Use your generated waveforms as a golden reference for your 5G design.

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.

Link-Level Simulation

Perform link-level simulations for the 5G NR Release 15. Perform transmitter, channel modeling, and receiver operations. Analyze link performance by computing block error rate (BLER) and throughput metrics.

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.

Test and Measurement

Build test models and characterize transmitter and receiver performance

RF Modeling and Testing

Evaluate the performance of 5G RF transmitters. Model and test NR RF receivers in the presence of interference.

EVM performance of a 5G NR RF transmitter.

Link Measurements

Characterize RF link performance. Measure adjacent channel leakage ratio (ACLR) and error vector magnitude (EVM) metrics.

ACLR measurement for 5G NR test models.

Downlink and Uplink Channels and Signals

Simulate 5G NR downlink and uplink processing. Configure and generate physical signals and channels.

Downlink and Uplink Channels

Create downlink and uplink physical channels including shared (PDSCH and PUSCH), control (PDCCH and PUCCH), random access (PRACH), and broadcast (PBCH) channels.

PUSCH and PUCCH channels.

Control Information and Transport Channels

Configure and generate downlink transport channels (BCH, DL-SCH) and uplink and downlink (UCI, DCI) control information.

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.

Cell Search Procedures

Perform cell search and selection procedures to obtain initial system information, including the Master Information Block (MIB).


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.

System-Level Simulation

Simulate frequency-time resource sharing among multiple user equipment in a 5G NR network.


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, Customizable Algorithms

Use 5G NR customizable and editable algorithms as golden references for design verification. Generate C code from open MATLAB algorithms using MATLAB Coder

Open MATLAB Code

Use transmitter, channel model, and receiver operations that are expressed as open and customizable MATLAB® code.

Open and customizable MATLAB code.

C and C++ Code Generation

Generate portable C or C++ source code, standalone executables, or standalone applications from your MATLAB applications that use 5G Toolbox.
