Abstract :
Traditional turbo-codes with BPSK modulation scheme, use equal error protection (EEP) for the turbo-encoder output bits. In this paper, it is shown that the role of the encoder output bits is not necessarily the same in determining the code performance. Imposing unequal error protection (UEP) on the output bits can result in improvement of the turbo-code performance
