This video contains a short summary of capabilities in the R2020a of 5G Toolbox, a MATLAB add-on product that enables users to model, simulate and test 5G wireless communications systems. 5G Toolbox provides users functions and tools for use cases such as waveform generation, link-level simulation, and golden reference design verifications.
5G Toolbox enables you to simulate, analyze, and test 5G communications systems.
The toolbox supports link-level simulation, waveform generation, golden reference design verification, and system-level simulation.
Using 5G Toolbox, you can generate uplink and downlink waveforms based on 5G NR subcarrier spacings, bandwidth parts and frame numerologies.
With the Wireless Waveform Generator app, you can generate 5G NR test models (NR-TMs) and downlink fixed reference channels (FRCs) for frequency ranges FR1 and FR2.
5G Toolbox includes functions to generate and configure 5G NR uplink and downlink shared channels, as well as control and broadcast channels.
You can also generate synchronization signals (PSS, SSS) and reference signals used for demodulation, phase tracking, channel state information, sounding reference signals, and the physical random access channel.
You can perform link-level simulations for 5G NR systems with transmitter, channel modeling, and receiver operations.
Using CDL and TDL channel models specified in the standards, you can compute the bit error rate, block error rate, and throughput metrics to verify your link performance.
You can perform practical and perfect channel and timing estimation, synchronization, and equalization including the use of deep learning techniques.
After generating a 5G NR test model, you can analyze your system by measuring the adjacent channel leakage power ratio (ACLR) to verify if you meet the standard requirements.
The LDPC and Polar Coding Subcomponents found in the toolbox provide functions to encode and decode transport channels and control information.
You can perform cell search and selection procedures to obtain initial system information such as the MIB and SIB1.
You can construct synchronization signal (SS) bursts and use DM-RS to synchronize the receive waveform.
You can perform system-level multi-node simulations, such as physical uplink shared channel (PUSCH) scheduling based on various medium access control (MAC) strategies.
You can access all 5G Toolbox features directly as open MATLAB source code and use these customizable algorithms as a golden reference for design verification.
5G Toolbox functions can be converted into C or C++ source code using MATLAB Coder. This enables you to accelerate simulation, access C source code directly, or use it as a standalone executable.
