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.

The MATLAB Codes were very informative and helpful. Can anyone please help to to implement a Wireless MIMO channel in MATLAB? You can send me at email@example.com.
It will be kind of you.
For those who have the following error :
Undefined function or variable 'randint'.
try replacing the line 21 : t_data=randint(9600,1)'; by : t_data=randi([0,1],9600,1)';
Undefined function or variable 'randint'.
Error in OFDM (line 21)
can u explain me pilt = 3+3j . why we are using it and contlen = 7 why only 7 y can't we take another
number. u can send the explanation content to my mail "firstname.lastname@example.org"
can't run the program. error has display like
Error in OFDM (line 26)
Nice work. I am writing a thesis on implementing radix 4 FFT algorithm for OFDM. I am new to simulink. Please anybody with sufficient knowledge on how to go about it should email me on email@example.com
Very nice work sir,
this is nice code please explain me this code line by line and suggest me what can i change in this code for my thesis work...its very veru urgent..please reply me soon..
Sir please tell me some other interleaving code for reducing BER.
Thanku sir. Sir can you send me mimo ofdm transceiver coding...My email is firstname.lastname@example.org
HOW CONVERT FROM 16QAM TO 64QAM
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 email@example.com .
thanks a lot..can u plz send me mimo-ofdm transceiver code.im currently doing my final year project..plz mail me firstname.lastname@example.org
I need code for ofdm signal which shows PAPR
can anyone please please email me line to line explanation of this code.PLEASE GUYs :(
Thanks for your source code,but I need source code about BER vs Eb/No ofdm with 4 QAM ,,please send to my email email@example.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: firstname.lastname@example.org
Thanks and regards,
hi pls tell me how to use qpsk in the same code instead of qam16 pls reply soon
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]...
hey please, any body tell me... how much bandwidth and symbol duration they used in this program..please please ...reply me to this id..email@example.com
please send me the global configuration parameter file
Plz just explain below line of ur coding
codegen = [171 133]; % Polynomial
I mean what codegen function does here.
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 firstname.lastname@example.org.
Thank you very much.
i request you to kindly explain the code line by line. please
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
Can you help me out in my project? What I need is An OFDM model with AWGN added and TDE, FDE and OFDE applied and then a performance comparison is done on the basis of BER...
It is helpfull
can you please send me the matlab code for ofdm using qpsk.. to my id email@example.com
i want code for Joint Decoding of LDPC Code and Phase Factors for OFDM Systems With PTS PAPR Reduction
pls can someone help me with matlab code for cancellation of ofdm sidelobes? thanks alot.
there is an error in line 49.
I want BER of OFDM MSK & DQPSK matlab code.. pls help
thanku very much
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
sorry! I was wrong! the code is perfectly working!!
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"
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!
It's very good!
