Abstract

This paper studies the mutual interference of wideband and narrowband CDMA in the mobile satellite communication system of narrowband CDMA overlaying on wideband CDMA

then it offers the best spectrum allocation of the two kinds of signals

and we find that the capacity of satellite mobile system will increase dramatically in our spectrum allocation.
