Abstract :
We consider the lossless compression of binary memoryless sources using a library of turbo codes. The message is compressed by each code and the best result along with the index of the applied code is sent to the decoder. Instead of transmitting the code index, we find a criterion to detect the code index using the transmitted parities. Our method helps to reduce the compression rate of short block length turbo source coders.
