CA 2291109

A turbo channel encoding/decoding device for a CDMA communication system. The device segments an input frame into multiple sub frames of an appropriate length when the input data frame is very long, and then encodes and decodes the sub frames. Otherwise, when the input data frames are very short, the device combines input frames into one super frame of an appropriate length and then encodes and decodes the super frame. After frame encoding/decoding, the frames are recombined into the original input frames.

L'invention concerne un dispositif de turbo codage/décodage d'un canal pour un système de communications à accès multiple par différence de code (AMDC). Le dispositif segmente une trame d'entrée en plusieurs sous-trames d'une longueur appropriée, lorsque la trame de données d'entrée est très longue, puis code et décode les sous-trames. Lorsque les trames d'entrée sont très courtes, le dispositif combine les trames d'entrée en une super-trame d'une longueur appropriée, puis code et décode la super-trame. Après le codage et le décodage de trame, les trames sont recombinées en trames d'entrée originales.
