Hi Omar,

As per my understanding you can follow the below steps to calculate MMSE channel estimation for WiFi 802.11g:

1. Generate the training sequence for WiFi 802.11g by using the WiFi waveform generator in MALTAB.
2. Transmit the training sequence over the wireless channel, and then receive the signal at the receiver.
3. Estimate the channel coefficients and then calculate the MMSE channel estimate.

Please have a look at the following MATLAB documentation for reference:

Generate WLAN waveform - MATLAB wlanWaveformGenerator (mathworks.com)

I hope the above information will be helpful in resolving your query. 

Thanks,

Muskan
