hi there I need a amtlab code for mimo- ofdm system thanks

01 Aug 2009 syed Haq

i m always getting 0 BER can anyone help me out with this and does anyone has the descriptiosn of this model

28 Jun 2009 syed Haq

can anyone help me with this model as m facing loads of errors while debugging this model

01 Nov 2008 Raaaghavan

hai sir its great,can you help me regarding the code for zeroforcing,mmse and Soft parallel interference cancellation algorithm in mimo ofdm(for cancelling spatial multiplexing interference).You can also mail me sir,my id is ramakokilam@yahoo.com

Can you inform me how to run this code?

thanx alot...

Hi. This is a good work. However, the simulation gives the same results in terms of BER when we choose to include either MIMO (Alamouti: 1) or not (SISO: 0) in the system. Can you please clarify this? Thanks

11 Apr 2008 kannan divya

no commants

08 Apr 2008 mikel mikel

sorry, i am usin r2007b

08 Apr 2008 mikel mikel

i get always a ber of 0 (no errors??)

also 3 warning in alamouti blocks

any solution? thanks

Salaam to all
Dear...anybody working about Space Time Coding in WiMax or near that field....let us make a research group.
I'm Master student in that field., contact me.

07 Mar 2008 Volker Richter

I really appreciate your work. It is an almost perfect model. But you didn’t configure the Reed-Solomon-Code properly. It is written in the IEEE 802.16 Standard, that the RS-Code is shortened and punctured. It’s not correct to ignore unnecessary redundancy bytes and set them to zero before decoding. You have to use a punctured RS-Code with a properly configured puncture vector. In your configuration bit errors appear, even though no noise is added to the channel.

As you have written in the readme-file, the configuration of the AWGN-Channel comes out of nowhere.

24 Feb 2008 mohamed kinawy

Really i donot have MATLAB R2007a to debug this model on it. but i sure that it work with no problems on R2006b

18 Feb 2008 aniket sawant

Your simulink model is Excellent, But while debugging ( R2007a ) i m getting following errors
1) Input port 1 of 'wimax/ALAMOUTI Transmitter/preamble/FIRST PREAMBLE/symbol 2' is not connected.
2) Output port 2 of 'wimax/ofdm de-assemble' is not connected.
3) Division by zero in 'wimax/ALAMOUTI Receiver/instead of ML detector/Math Function13'.

Please tell me how to remove these errors.

15 Feb 2008 harish pandey

Good Work, But i think I am missing some information. can you please what key you use to calculate BER.

21 Jan 2008 aakif qazi

It is good work to implement the MIMO. But model looks very much a copy of WiMAX 802.16e Physical Layer posted on the User Community, if this is the case then you need to acknowledge that work while you post your model

04 Oct 2007 mohamed kinawy

Its logical that the model is looklike WiMAX 802.16e model because its the same physical layer and the same standard (802.16).
This model is finished at 1/7/2007 but we late in publishing it.
When we start work at this model we didnot found any models about fixed wimax the only models is for wifi.
