Abstract :
We discuss the application of trellis coding in a (direct sequence spread spectrum) CDMA system where orthogonal signaling is used. Our approach is to construct the trellis codes over the set of biorthogonal sequences. A general analysis is presented. We compared the analysis with computer simulation. The results show that the trellis coded CDMA system outperforms the corresponding uncoded DS/SSMA system
