Re: [802.3_EPOC] OFDMA information
Leo,
I think the description of OFDM vs OFDMA in this page http://www.rfwireless-world.com/Articles/OFDM_versus_OFDMA.html is relevant to our discussion.

Hal,
The text is from slide 9 of the presentation. I am not sure what was the author intention, the diagram does not agree with the text. I will recommend the following change:
"Frequency sub-channels are composed of multiple sub-carriers."
Thanks
Leo

Leo,
* The document you sent says, "Frequency sub-channels are composed of multiple, non-adjacent carriers"
The diagram seems to indicate that the sub-channels are composed of multiple, adjacent carriers.
Can you clarify the statement quoted above?
Thanks,
Hal

This is not a proposal for OFDMA. This information is to help defining what is OFDMA.
OFDMA: Multiple Access scheme using Orthogonal Frequency-Division Multiplexing where sub-channels are allocated in the frequency domain. The sub-channels are allocated to individual users.
Thank you
