...having said that, I never saw the trigger jitter until I started using a random data source rather than 'range(packet_len)', do you get jitter in this case?

Ah, I see. You want to isolate the effect of the channel. I believe it will be difficult, if not impossible, to remove the slight jitter of the trigger, even in very high SNR - perhaps others can comment/help?

Aditya - am I to understand that you want to have perfect timing sync?
Correct. This is because I want to study how the channel changes across OFDM subcarriers (caused due to multi-path). Having rotations in the channel across subcarriers caused by trigger timing offsets is what I want to eliminate.
best,
aditya
