 10 Aug 2006 6:05 COMPLETE Turbo Code Demo IN MATLAB (usefull for wimax) |

MATLAB code for experiment on turbo codes
The following MATLAB funtions will allow you to simulate the classical Turbo Coding system, which is also known as parallel concantenated convolutional codes. They are written to be shared with fellow researchers working on Turbo Codes. Please download all the .m files and run turbo_sys_demo.m file in MATLAB environment.
--------------------------------------------------------------------------------
This NEW version includes both the Log-MAP [1] and SOVA [2] algorithms for decoding. The information bits are randomly generated which assume a uniform distribution. For each frame of bits, a random interleaver is generated for it. Thus the code performance stands for the average performance among all interleavers. You can set the following parameters yourself:
decoding algorithm ( Log-MAP / SOVA )
frame size code generator puncture / unpuncture
maximum number of iterations number of frame errors to terminate signal to noise ratio ( Eb / No )

The link h**p://www.ee.vt.edu/~yufei/turbo/log_mapo.m
should be h**p://www.ee.vt.edu/~yufei/turbo/logmapo.m

Hello thank you for the information.
i TRIED the matlab program for turbo codes demo but it was working and it gives me results only for frame size of 1024 bites.
but it s not working for 65536 bits.
Please can you help to see the problem on this turbo codes demo from yufei.
witting for your response
regards.
