Structure of a complete radio transmission link
A radio transmission link can be divided into individual function blocks. They work together on different levels with the corresponding counterpart. These blocks are the transmitter/receiver, channel coding/decoding, source coding/decoding and signal source/sink. You can download the Simulink model* of the complete radio transmission path here.
Explanatory videos have been created for the individual blocks:

* The Matlab /Simulink models are created in version R2021a. It may be necessary to install the appropriate hardware support package in addition to the Communication Toolbox before starting a simulation. Our models use the RTL-SDR, the USRP radio and the ADALM-Pluto package.
