Abstract :
This paper examines the potential of turbo-codes over non-binary rings. Good component codes are chosen, and simulation results presented. Codes over a number of small rings were examined. The authors consider turbo codes constructed from non-binary component codes concatenated via a random symbol interleaver and mapped onto the appropriate q-ary-PSK constellation for transmission through the AWGN channel. The domain considered is rate 1/3 turbo-codes with identical rate 1/2 RSC component codes.
