Downlink Channels

5G NR downlink physical channels and signals, transport channels, and control information

Use 5G Toolbox™ downlink channel processing functions to:

Create physical signals and channels for transmission and reception.
Create, encode, and decode transport channels.
Encode and decode downlink control information messages.

Use these functions as golden reference for verification and conformance testing when implementing the downlink processing chain of NR systems and devices. You can also modify and customize the functions and use them as custom reference models in your implementation.
