EXIT chart computation

Matlab class implementing several methods for the computation of EXIT charts.

Description

EXtrinsic Information Transfer (EXIT) charts are useful for characterizing the convergence properties and the performance of turbo receivers. Turbo receivers are generally constructed from two or more Soft Input Soft Output (SISO) modules. By simulating a single SISO module, the transfer characteristic of the SISO module can be obtained using the EXIT class. The transfer characteristics of two SISO modules represented on the same figure by switching the axes give the EXIT chart.

• Required Products: Communications System Toolbox
• MATLAB release: MATLAB 7.8 (R2009a)

I think the code rate R should be equal to 1/2 not 1/3

[Bogdan Cristea]

R is the rate of the turbo code, which has a rate of 1/3 when there is no puncturing pattern

Thank you for your valuable code.
For matlab simulation using C_SISOsova.cpp, I need dll file.
However, Even after several attemps using mex, I cannot generate dll file.
If it is possible, could you send me dll files for C_SISOsova.cpp
& C_SISOrsc.cpp? Please, give me help.
P.S. : I am not familiar with usage of mex.
         Matlab command window continuly complains as following message. Could you give me solution?
fatal error C1083: Cannot open include file: 'itpp/itmex.h': No such file or directory

[Bogdan Cristea]

The cpp file you are using is not included in the archive from MATLAB central. C_SISOrsc.cpp uses algorithms now included into IT++ library. You should either install IT++ library before trying to compile that file, or customize yourself SOVA implementation in order to become independent from IT++.
