O-RAN Modeling and Simulation with MATLAB

Overview

In this webinar, we showcase new functionality in MATLAB to model and simulate the open radio access network (O-RAN) technology. First, we provide an overview of the O-RAN standard and its specifications. This includes a discussion about the role of Radio Unit (RU) and Distributed Unit (DU) system components and how they communicate with each other using the Enhanced Common Public Radio Interface (eCPRI) protocol. You learn how to use 5G Toolbox to generate and decode those packets. You will also learn how to examine the impact of O-RAN compression algorithms on the overall performance using metrics such as EVM. 

Highlights

Through example you learn how to:

• Generate O-RAN 7.2x split
• Apply O-RAN compression techniques such as block floating-point, block scaling and mu-law
• Encapsulate the compressed data into eCPRI packets using pcapWriter function
• Perform decoding operations on the packets using pcapReader function to obtain the compressed data
• Decompress the data and recover the best estimate of the O-RAN 7.2x split
• Optionally, examine the impact of this process on the overall EVM performance
