I have finish an OFDM program in Matlab, now I wan to modify it into a MIMO-OFDM, could anybody tell me where I should modify? channel matrix?

MIMO-OFDM

now, if you want to modify to a MIMO-OFDM, you should research Space time code or V-BLAST ... because these relate to MIMO. You have finished OFDM program that is you finished modulating/demodulating,IFFT/FFT and fading channel. However, to finish MIMO-OFDM you also should read Maximum Likelihood. after investigated i think you have the ideas to advance your program.

Goodluck!

removed!
some channel coefficients:
(exp: exponential or SUI4 or Cost207 or ...).

Re: MIMO-OFDM

hi totohaha , just split the input vectors may be as alternate bits depending on the number of transmitters ,transmit through the fading channel,on the reciver side detect the bits using V-BLAST algorithm,will work fine

Hi totohaha,
Could you please send me the OFDM syntax, because I am working on it, and I have difficulties to design an OFDM system with multipath fading.
Very thanks in advance.
sh.

Re: MIMO-OFDM

I am a telecommunication students and interested in OFDM.
I am still studying OFDM. Please may you send me your MATLAB codes for OFDM? so that I can even see the plot for Eb/No versus SNR or BER performance or any other performance analysis.
Thanks

Re: MIMO-OFDM

What is the differences between MIMO and MIMO-OFDM and their advantages... give some points...

IN what way MIMO-OFDM is efficient than MIMO...

iam thinking we hve to modification at the transmitter side... that is before modulation...

Re: MIMO-OFDM

you should divide the transmitted data into Mt bit stream. after modulation with OFDM you should transmit the modulated signals through MIMO channel

Re: MIMO-OFDM

1. Why precoding requires knowledge of the channel state information (CSI) at the transmitter.

2. what is the importance of CSI and Wht are their parameters?

al salam 3alycom,
i want to ask that i use dvbt-sim but the input to this system is come from birnolli source but i want to enter the output from video source so how can i convert the output from Video source to mpeg stream on matlab simulink?
thanks
