GSM Traffic Channel Simulator



14 May 2006 (Updated )

Simulator for a GSM traffic channel transmission and reception

| Watch this File

File Information

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.


Tch/Fs Gsm Channel Simulation and Gmsk Transmission inspired this file.

Required Products Communications Blockset
DSP System Toolbox

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.

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?

I have the following error :

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

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

10 Nov 2008 Kamal

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?

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?

22 Jul 2008 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.

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

14 Nov 2006 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.

16 Oct 2006 Geetha S

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

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