I'm just afraid of nasty fat patent trolls...
Pilots forming this channel characteristics for STC, isn't it?..
P.S.
Превед ^_^ Ты из питера? Что вы разрабатываете, колись :)
Hello!If I want to create 802.16e compatible base station "from zero", i.e. all layers including PHY - does it dangerous with patents? How to overcome all patent problems at no cost? For example - if opensource project or any other ways...And anothe…
By the way, do we need to create subcarrier indexes for every OFDMA symbol, or it is possible to create some intermediate calculations and then match them to current symbol? It's for computing simplification purposes...
Oh... "DL PUSC" permutation and all other permutations in this standard is a hard pain... It almost impossible to calculate indexes of subchannels correctly when watching standard.
Sorry for delay...
Please, explain me *.dat format. What is it???
How you reading this? Show me your code if you can or at least short description of this format... Sorry, I do not have libastral.so installed in my brain ^_^
Can you send me this signal on mail? I'll watch it ;)
Your Fd is 11200 KHz? ;)
PS
May be spectrum inversion? ^_^
Try to compare from other "side" of spectrum...
Did you rotated your spectrum by 512 samples (of 1024 total)?
It also called "pipelined" model. Just pipeline... You can see this structure in many devices, processors, etc...

Balaganapathi.M said… - Hi alex,
Can you clear me about the relation between Packet Arrival Time and OFDM Frame Duration. Is there any condition on the OFDM Frame duration and Packet Arrival time both needs to be same. Is it possible to have G711 voice codec with 20ms Packet arrival time and 10ms OFDM Frame Duration.
Please reply for this, becuase am in a confusion.
Thanks,
Balaganapathi.M
