Hi Baris,
To simulate WiFi 6 with channel assignment and carrier aggregation and obtain BER and SNR values, you can use MATLAB "wireless Waveform Generator" for the transmitter simulation. Type the below command in the MATLAB command window to do so:
wirelessWaveformGenerator
In the tool, select "802.11ax" as the Waveform type to simulate WiFi 6.
For specifying the SNR value, enable the AWGN option in the Impairments section of the generator. This tool also lets you adjust various parameters like Frequency offset and Guard band to closely match your simulation needs.
At the receiver side, to understand how to handle the received signal and extract the desired metrics like BER, please refer to the following example:
