turbo codes vs ldpc codes

turbo ldpc

hello guyz....

there's a project that need 2 b d0ne here in my uni...
well....i need to find differences between turbo codes and ldpc codes in wireless channel using matlab...

these are my specific task...
• number of iteration
o how the bit error rate (BER) will change as the iteration is increase compared to SNR

• modulation techniques
o comparison between QAM and QPSK therefore try to increase the constellation of the modulation scheme for the effect of various coding rate to compare the achievable performance between 2 codes
o what is the changes to the BER compared to SNR as we change the modulation techniques and their constellation

• effect of code length used (input block length of codes)
o to investigate for difference of delays


• Comparison in wireless communication channel
o using Rayleigh fading channel

i really hope u guyz can help me to find out the matlab source code in finding the differences of turbo codes n ldpc in the specific task given

thank u...really appreciate it
