\page exit_pccc EXIT chart of PCCCs
This program computes the EXtrinsic Information Transfer (EXIT) chart for
Parallel Concatenated Convolutional Codes (PCCCs) of coding rate 1/3. Actually the Transfer Characteristics
(TCs) of the two SISO RSC modules used in the turbo decoder are computed at a given Signal to Noise Ratio (SNR).
Reference: S. ten Brink, ''Convergence behavior of iteratively decoded parallel concatenated codes,`` IEEE Transactions on Communications, vol. 49, pp. 1727-1737, Oct. 2001
\include exit_pccc.cpp
When you run this program, the results (mutual a priori and extrinsic information, EbN0_dB, etc.) are saved into exit_pccc.it file.
Using the following MATLAB script
\code
clear all
itload('exit_pccc.it')
plot(IA, IE, 'LineWidth', 3)
hold on
plot(IE_p, IA, 'LineWidth', 3)
xlabel('I_A^{(up)}, I_E^{(low)}')
ylabel('I_E^{(up)}, I_A^{(low)}')
grid on
title(['E_b/N_0 = ' num2str(EbN0_dB) ' dB'])
\endcode
the EXIT chart can be displayed.
