Live Q&A - FlexLink, a Practical OFDM Datalink, Introduction and Python Demonstrations
Leonard Dieguez- Recording Soon Available - EOC 2024
He should be in the live Q&A session on the 30th. There are probably some interesting things you can do if the data rate is slow. One thought would be replicate the data or "spread" the data across multiple ofdm symbols and bins. This could allow you to lower the overall signal power output as well. This is meant to be a framework starting point for people that wish to design custom datalinks. We are still refining the "spec" and working on receiver sections. Overall someone could tailor the datalink to operate in lower bands and use less data or bandwidth.
Thank you for the presentation. I am curious as to how much frequency and sampling rate error in ppm can be supported by this preamble design. 20 years ago, I remember having to do coarse then fine frequency offset acquisition followed by phase tracking. It is not obvious that coarse and fine acquisition are both possible in this air interface and the sub carrier spacing is pretty narrow, so I was wondering how this is achieved. Thank you.
