Re: Question For MIMO gurus
Hi,
This Could be the ansswer for this question:
In general Bandwidth Efficiency means : C/BW
C - Channel Capacity ; BW - Bandwidth
In case of MIMO this ration will boost up by a factor of rank(H) where H is the channel matrix (this again depends on the type of...
ofdma subchannelization
Tiles are also like our time slots but they do have restrictions in subcarriers direction..i.e our Tiles are SymbolsXSubcarriers Matrix.Mostly per each tile we are assigning 48 subcarriers.These tiles only we are using for scheduling.
In Single carrier case we don't...
Re: resource allocation
Resource allocation in OFDM means based on subcarrier SNR we are selecting modulation scheme i.e Channel State Information should be available at the Tx such that modulation shcemes can be adapted...
Hi friends,
Please help how to proceed scheduling OFDMA slots using Proportional Fair shceduling...How to calculate throughput and Delay?
Thanks in advance

hi,
I hope these might be correct ,cross check once...
Signal bandwidth/Subcarrier Spacing -312kHz
channel bandwidth---20MHz
carrier frequency --- 2.4 ghz
sampling frequency(fs) ---20Msps
doppler frequency --- Its depends on Velocity( with in 10kmph)=v/lambda
V is velocity in m/sec...
Hi Friends,
Anybody please tell me how to generate Poisson Traffic in WiMAX for different Applications like UGS,rtPS,nrtPS...?How to calculate scheduling delay in Proportional Fair scheduling simulation..?
Thanks,
Taraka
have 10 % of uplink then downlink
I think these rates are depends on the type of applications and type of communications...
I find in WiMAX(broadband wireless) DL rates are higher than UL since in the UL we are getting only BW requsts and control messages...in DL only data flow..applications...
satellite uplink rates
Hi Friends,
Please clarify this doubt.
Why Downlink Rates are higher than Uplink rates?
Thanks in Advance..

Dear Friends,
I am beginner to WiMAX.I want to know the clear details about the TDD frame structure in WiMAX.
What is the difference between Symbol and Subchannel?
They are mentioning 24 sucarriers over 2 OFDM symobls ..
It means 48subcarriers or differnt?
Please give me clear Idea...
alamouti scheme matlab
Hi ,
First u go through the IEEE paper by Alamouti .
"A Simple Transmit Diversity Technique for Wireless Communications" IEEE October 1998
It ll give you basic idea of implementing the Alamouti scheme.
All the Best

Taraka
Hi i friends,
I have one doubt in OFDM.We are using IFFT for the purpose of baseband modulation.The function of the IFFT is to convert Frequency domain to timedomain.But how we are giving the input in frequency domain.
1)We are generating data
2)Applying modulation
3)Applying IFFT
Where the...
