Mistake => Check below.
QPSK 1/2 = 1 bit/ tone = 6 bytes / subchannel (1 DL PUSC subchannel have 48 data tones)
QPSK 3/4 = 1.5 bits/ tone = 9 bytes / subchannel
16QAM 1/2 = 2 bits/ tone = 12 bytes / subchannel
...
64QAM 5/6 = 5 bits/tone = 30 bytes…
What kind of capacity do you want to calculate?
If you want to calculate the real(-_-; somewhat not real) numbers of sessions(users).
You should first check how many MAP-IE's can be made in your profile and how many
sub-channels are possible in DL a…
Oh... This is something effective for me to say everyone about WiMAX.
I will start the introduction about WiMAX tech.

This is Jay, from Bangalore, India.
It might be a basic question for you, but I don't have a clear vicinity over this.
Why 8/7 or 28/25 oversampling in WiMAX? What we can actually achieve from this? Can you please throw me some light on this?
Thanks in advance.
Regards,
Jai..

Farha said… - Hi Mr Donghun Kim.Thanks for accepting my invitation. Yes I do have a few questions would like to ask.
Since you are involve in RF optimization, may I ask how can i know the threshold value for RSSI specifically for wimax 802.16e?
To do the optimization what's the parameter that need to change? Is it the same as 3G ? Like the antenna heigh..transmit power and so on?
Kamsahamnida..(",)..Correct me if Im wrong. TQ
