Re: [STDS-802-16] Fwd: [STDS-802-16] [PREAMBLE] reasonings for OMI

Title: Samsung Enterprise Portal mySingle
Hi Jiho,
 
I have some comments on your assumptions per your points:
1) As you stated FUSC uses all bandwidth but so can the PUSC, so you may trade BW/footprint and Interference as you like.
2) I am not sure the O-FUSC meets all the spectral masks (I am not sure such an analyses has been done, or at lease
I didn't see any), and it is gets very hard implementing these much carriers (more processing in some digital mechanisms
due to so much used BW). But if I am wrong then you are right.
3) The assumption of the hit probability must be between subchannels but if you use all the spectrum, you are hitting all
subcarriers all the time anyway (and I am not sure that the hit probability will be such a factor in this case - where different permutations
will be used for the PUSC zones, excluding the first 2 symbols).
4) Diversity gain difference is very small as the PUSC already has clusters scattered all over the spectrum, the difference will be between 24
clusters each with 2 subcarriers and 48 individual subcarriers.
 
And in any case you can switch zones just after the first 2 PUSC symbols, which are heavily coded, has better S/N and better
foot print when used in the 1/3 configuration.

Yossi

Hi all,

 

I'm Jiho Jang from Samsung Electronics.

 

I have uploaded a material which describes the reasoning for the proposal of OMI (operating mode identification) for your information on http://temp.wirelessman.org.

Please find the uploaded file and look it over. Thanks.

 

Regards,

 

Jiho Jang
