Abstract :
Non-binary turbo codes are built from recursive systematic convolutional (RSC) component codes with m inputs (m⩾2). This construction offers better performance than classical binary turbo codes, especially at very low BER and high coding rate. Some examples with rate 2/3 are given on 8-state and 16-state duo-binary turbo code associated with QPSK and 8-PSK modulation
