Abstract
A new coding/modulation arrangement for up-link direct-sequence code division multiple access (DS-CDMA) communication, which employs coherent detection with reference-symbol based channel estimation, is presented. It is shown that the required E/sub b//N/sub O/ for this scheme is about 2 dB to 2.5 dB lower than non-coherent detection of Walsh coding with bit interleaving and about 1 dB to 1.3 dB lower than noncoherent detection with Walsh symbol interleaving over the entire range of practical vehicle speeds. A frequency domain analysis of this scheme is given.Keywords
