This code basically computes the BER of an OFDM system. The ifft size is 64 .16-QAM is the modulation Technique and convolution encoding rate 1/2 is used as the coding scheme.

Thank you very much. I have to use QPSK modulation in OFDM system. After that, I want to introduce some random carrier frequency offsets in various sub carrier frequencies. This offset may be modeled by a Gaussian RV with rms value equal to 1/3 to 1/2 percent of the frequency spacing. Can anybody please help me with that, Please guy's, my email id is onkarvpatil15@gmail.com .

thanks a lot..can u plz send me mimo-ofdm transceiver code.im currently doing my final year project..plz mail me kanibeece@gmail.com

Sir, How can we make it highly computationally efficient using shifting and switching technic. I need the theory part and coding to study.
Please send it on my e-mail: shreyasbharati@gmail.com
Thanks and regards,

hi pls tell me how to use qpsk in the same code instead of qam16 pls reply soon

sania sss

santosh, they using 1/2 code rate, means k/n form ,1 is the single input and 2 is the output in the form of adders and they are using 7 memory register , after implementing this , u wil get [171 133]...

sania sss

hey please, any body tell me... how much bandwidth and symbol duration they used in this program..please please ...reply me to this id..saniasss212@gmail.com

Fauza Khair

hey ,
please send me the global configuration parameter file

fauzakhair.maya@gmail.com

Santosh

Plz just explain below line of ur coding
codegen = [171 133]; % Polynomial

I mean what codegen function does here.

Hello dear
please help me i need m file for
General MIMO-OFDM with QAM modulation tech. result should me compaision of V-Blast.MMSE, ZF w.r.t BER v/s SNR

Hello . My name is Abylay . I undergraduate Almaty University of Power Engineering and Telecommunication. I am currently working on a dissertation on LTE, namely the creation of a simulation model of OFDM and OCDM on MATLAB. Can you help me ? Please contact me at my e-mail address abylay.samenov@gmail.com.
Thank you very much.

Please I have been trying to write a code to generate an OFDM baseband signal and also to find the PAPR of the signal and its spectrum but its been fruitless getting frustrated, plz any ideas?

sir can u pls send me code for channel estimation of ofdm

sir the code is showing an error in line 26 that the index is out of order matrix dimension please help me

was very yousful

hi every body.i had 1 proplem about the ofdm simulate.this is the last year i study at shool.so i have 1 project that about OFDM.but i did'nt know how to simulate that.some one cuold show me.thanks alot.and what'll i do first?

how can it working.that just demo.they cut some where in the code

Kaushik

sorry! I was wrong! the code is perfectly working!!

Kaushik

I found a problem with this code.
When no noise is added and when the rxed_data is collected for every frame, then there is an error when compared to t_data

can any one help me in this topic"Interference Suppression for OFDM Systems With
Insufficient Guard Interval Using Null Subcarriers"

Suhail Khalid

Well done! A few parts I feel could be done better (specifically the choice of using trellis and pilot insertion) but all in all quite straight forward and easily understood. Thanks!
