Joint decoding of serially concatenated coded CDMA: iterative schedule study

Zhenning Shi, Christian Schlegel

Abstract

Joint iterative decoding of forward error control (FEC) encoded code-division multiple-access (CDMA) systems is studied. Serially concatenated convolutional codes are used as FEC codes. We apply iterative decoding to this system and study the effect of component decoders and different decoding partition schemes via a variance transfer analysis. It is shown that distinct partition schemes result in similar pinch off SNRs.
