Characteristics of a sixteen-state turbo-encoder/decoder (Turbo4)

Résumé

This paper presents the characteristics of an integrated circuit called "turbo4" which can be used as a turbo-encoder or as a turbo-decoder. The turbo-encoder is built using a parallel concatenation of two recursive systematic convolutional codes with constraint length K=5. The turbo-decoder is cascadable, each circuit processing one iteration of the turbo-decoding algorithm. It is designed around 2 sixteen-modified Viterbi decoders and 2 matrices of 64 x 32 bits for interleaving and deinterleaving. Some measures for Gaussian and Rayleigh channels and for different coding rates are presented.
