CDMA network design
9.1 BASIC SYSTEM DESIGN PHILOSOPHY
In Code Division Multiple Access (CDMA) systems, the capacity increase is based on how much interference the desired signal can tolerate. Prior to despreading, the signal level of a desired signal is always below the interference level. All the users have to share the same radio channel. If one user takes more power than needed, then the others will suffer and the system capacity will be reduced. In analog and TDMA systems, the most important key element is the carrier to interference ratio (C/I ). There are two different kinds of C/I . One...
