I am having difficulty locating an example Pulse shape used in the standards:
802.11 a/g/j
802.11 b/g
802.11 p
802.11 n/ac
I found an example pulse shape for 802.11 ad : 802.11ad Transmitter Spectral Emission Mask Testing - MATLAB & Simulink (mathworks.com)
However, I need it for the other standards. I tried obtaining it from the Wireless Waveform Generator App:
However, I don't see a clear example of the pulse shaping being utilized ( like how it is in the 802.11 ad example).
Could you please instruct me to where I can find it?

After spending some time on this, I've come to the following understanding:
The IEEE 802.11 standards with OFDM have inherent rectangular pulse shaping per subcarrier via the IFFT. There have been mentions of changing this in some research works, but standard applications ( Ex: USRP ) follow this.
The IEEE 802.11 standards without OFDM ( ex: IEEE 802.11 b and IEEE 802.11 ad ( for given MCS configurations ) ), a pulse shape is implemented on the single carrier, conforming to the spectral mask requirements.
As for what the pulse shape looks like: That is left to how the user wishes to implement it. It can be raised cosine, root raised cosine, etc. The choice is left to the implementer.
The standards (upto IEEE 802.11 - 2020 ) do not have a constraint for how the pulse shape should be implemented.
