Simulator for a GSM traffic channel transmission and reception

36 Ratings



No License

This Simulink model simulates the entire transmission and reception of voice data of a traffic channel for GSM (TCH/FS)over a multipath fading channel, and it calculates the BER of the received signal.

The system cannot find the path specified.

I am getting this error, can't resolve by myself. Can anyone help me out?

Would you please send me the source code? This could be really helpful to me.

Hi, I need the source code to modify it. Is it possible for you to share the source code with me. Also, when I tried to run code, I received and error about rayleigh fading blocked and I couldn't run it. Any idea? My email is I really appreciate it.

Hello. Could you send me this simulink model with the source code ? It will save me (: Thanks

what a wonder job,thanks a lot

this simulation is great , thank you
i would like to understand your code more , could you please send me a guide or something to make it more clear
thank you

I need to use the GSM channel for simulation.

Please e-mail the code on

Does anyone have the m-files version instead of simulink?

beh ghor

I need this simulink. pleas send to my email.

Hi, I'm just wondering if this model can be modified to take in PCM audio data from a .wav file as an input and output .wav data that is a simulation of GSM channel noise? I've never used Simulink before, but would it be as easy as changing the Bernoulli Binary input to a vector filled with the audio data? Could the output then be collected, or have I misunderstood the purpose of this simulation?

WARID Zaheer

Hi ! I need a file which can show GSM frequqncy hopping MAIO simulation ..

i need th m file of the gsm simulation

I have the following error :
Error reported by S-function 'sdspsigattrib' in 'GSM_Blocks_ENG/background6/Multipath Rayleigh Fading/Multipath Fading Channel/Multiple Delayed Signals/Check signal is frame or vector/Check Signal Attributes': Input must be a column vector.

Great!!!! Thanks for this work. Have you worked on that for your job ? What can be the applications ? Thanks !!!!

It's possible receive documentation of receiver?

I am just a beginner. Could you please give me some guidelines on how to start off? I would really appreciate your help.

Thank you.

P.S. I need your help BADLY.

Yushu Zhang

i want to use this application but i'm just a biginner in matlab, and never used simulink in it, can anyone help me to use it plz?
i'll be greatfull if someone woul help me

Oops, the model performs hard decision decoding since the viterbi decoder is set to perform hard decision decoding.
I think the interleaver does not performs diagonal interleaving since it does not consider 2 particular speech slice during any interleaving part.

Does anyone has the m file version of the gsm TCH model


Kamal (view profile)

hello, the model performs soft decision decoding of the GSM system.
How can we perform soft decision decording?
Should we put the diferential encoder part before the encoder at the TX and differential decoder after the decoder part at the RX?

Does anyone have the m-files version instead of simulink?

rohit datta


I went through your codex.

its nice. how can you see the GSM signal that is transmitted through the channel? do we need to have a scope?

Adetosin Adetunji

I highly grateful for this opportunity given,so,its pleasure.
Could you please send me Free GSM Simulator through my email address.
Thanks in Advance.

pradeep gautam

i have gone through this blocks..
its interesting can u pls send the docs related to this model

kiran rangineni

I have gone throgugh the blocks, its perfectly strutured, Could please send me the docs and code of the files which will be very helpful for my project.

sree r

i working on this .. can u send the code&related documents

dickson ntogha

osamaali abdulla

hello sir can you please tell me what version u used and the documentation to understand that please

muhammad touseef

hello sir,can u send me the exact simulation for the call routing of GSM(wireless),plz do this as soon as that it is helpfu for me

sh3esh3 sh3esh3

I am not able to run the program. Lot of warning messages appears:S:S:S
error in open it
plz solve this problem:S:S:S

Alex Silva

I would like to understand your code. Can you send me the documentation whatever you used.

Bouafsoun Hamdi

thx first,i want to ask if you simulate 4 normal burst (4 user) or no ?

thaer abu alheija


sanjay dabhole

to understand your code can you send documation or theorotical approach whatever you used sot that i will check the accuracy

Santosh Shah

Dear sir
your program is to good, i run this but the problem is that, the ciphering, and deciphering technique is not involved, ant the gard bit among the burst is 9, but in actul it is 8.25. so tell me is it any possiblility to do that, with 8.25 bits gard.

thanking you.

Geetha S

I am not able to run the program. Lot of warning messages appears. I have MATLAB 6.0.

Please reply ASAP.

It's very good. It simulates the entire physical layer of GSM
