Great ^^

[sidra jabeen]

Hi,
I m interested in OFDM simulation. This is a very good and helpful model. Please send me description document of the ,model.

[triet ho]

i am using matlab version r2010a. i downloaded your file then i ran it but it doesn't work? please help me.
everybody can answer my question please!

nice 1

[Olexander Zhytenko]

very nice

[Gito Prastomo]

Joe,

You are correct, the main of my project was to compare the channel estimation methode by training and pilot signal.
Training signal methode is not bw efficient like in the model.
Pilot signal -> i inserted some pilot on certain subcarriers then interpolated them to have channel response -> this very good for fast fading channel. I havent submitted it yet

[Infant Joe Charles]

In this method, you used one training symbol for every OFDM symbol. This is not bandwidth efficient. only 50% of the channel capacity is actually used for data transmission. The remaining is used to send data. Now, is there a way to transmit one training symbol for say, 10 OFDM symbols.

[Chiara Risi]

Hi,as a lot of people above I'd like to have the description of this model!
Thank you very much,
Chiara ([e-mail])

[Infant Joe Charles]

Hi,
I can't see the spectrum. Can you tell me how to see the ofdm spectrum?

[Gito Prastomo]

Hi All,

I uploaded new email contact. If you have any queries, just drop email to the email.

[quy nguyenminh]

first i wanna say thanks a lot to owner who written the code.so i didn'd understan after i dowloaded then open to used.have some problem.i cuoldn't play,because it's apear 1 message.that's some block unknow.cuold u show me how can i do in case.i used the matlab version 7.7.thanks!

[steven Huynh]

Hi friend,

I am a student from Vietnam. And I am studying OFDM for my undergraduate thesis.

I have downloaded your model at Matlab central. There is some information I still cannot understand in your model. Therefore, I hope you could explain to me.

The first question is:
In Bernoulli Binary Generator, you set parameters:

Initial seed: 9364248
Sample time: 16e-5/44/2

Why?

I am looking forward to hearing from you.

Yours Sincerely,

Steven Huynh

[Gito Prastomo]

Hi All,

This is Gito, sorry for late response about some issues which rise by Shari.
My mail has lot of Bulk, so i rarely check it.
Actually, the problem on the switch_off.jpg etc, might be due to the picture, so it is recommended to delete all switches picture. All switched is used for showing the spectrum and time scope. To show this spectrum and scope, you can find it all inside the block, i forget which block it is.

THanks// br
Gito

[Shari Freedman]

Hello Gito,

I am trying to get in touch with you regarding an issue that one of the users has discovered. Unfortunately, your email was undeliverable. He believes that there is a missing file which is necessary to make your program work: switch_off.jpg.

Please email me at [e-mail]
Thank you,
Shari
