## Re: research project

hi, i get info abut ofdm, MINO using adapative bit , i want more info regarding ofdm (orthogonal ferquency division multiplexing),but my prob.is i want more tech. abut ofdm.

thanks for your kindly co operation

## Re: research project

well, both are different areas. If you are a comm. engineer or are interested in it, I strongly suggest you go for the ofdm-mimo one.

Decide and then I will guide you through it.

## Re: research project

ok.

For OFDM visit dspLog - Signal processing for communication and try to understand how OFDM works. You will also find a Matlab code for it and this will clear your concepts further.

Put your questions here regarding OFDM if you have any, I'll try to help ;)

Once you complete OFDM, you can start on MIMO but for now concentrate only on OFDM

## Re: Research project using matlab base , for BE

thank you so much ,,

,i want to incerase the BER rate of mimo ofdm (more than 10^-5b ),, which method is suitable, bcoz in our college we want give method name for improving the ber.( adapative bit method i kw ,,it wil work ?plz suggest)

i got high throughput of wimax MIMO OFDM Ieee paper 2010,, shall i go for that

## Re: Research project using matlab base , for BE

what do you mean more that 1e-5?

Do you mean that the y-axis stops at this point? Please explain your query

## Re: Research project using matlab base , for BE

1.plz suggest me which method is suitable(its urgent)

2.bcoz my senior used LDPC tech., THEY achieved BER of 10-5 at matrix length of 1000x2000 for 2 iterations at Eb/No=3dB.

3.i want to do based on ofdm,

4.what suggestion u hv abut performance of adaptive bit n power allocation mimo ofdm using greedy algo.

5.i got high throughput of wimax MIMO OFDM Ieee paper 2010,, shall i go for that

sorry for inconvi.

## Re: Research project using matlab base , for BE

4 & 5: Like I said before, first learn OFDM if you want to work on it. Take one step at a time.

I think you senior did simulation of LDPC in awgn and not in Rayeigh... which you can do with OFDM.

## Re: Research project using matlab base , for BE

can you simulate OFDM in AWGN and Rayleigh fading channel?

If so, please add MIMO transmission to OFDM and find the performance over Rayleigh fading channel.

Once you finish this then proceed to adaptive power allocation for mimo-ofdm.

*By the way, how much time do you have before you need to submit your BE thesis?*

## Re: Research project using matlab base , for BE

hi

i m doing mimo ofdm project

with fec coding

bt i m not geting propr ber curve

it is coming constant with 0.5

are u having any code with mimo ofdm ber for qpsk

plz mail to priyanka269085@gmail.com

need it urgent
