N2  - This thesis presents a novel one-persistent idle signal-casting spread spectrum with  overload detection protocol (IP-ICSS/OD) for CDMA cellular networks. It is based on the  modification of an existing narrowband scheme, i.e. one persistent signal-casting multiple access  with collision detection (IP-ICMA/CD), to work in CDMA systems. However, the more efficient  CDMA packet access strategy, named as one persistent carrier sense spread spectrum with  overload detection (lP-CSSS/OD), has already been proposed but for optical LAN networks.  Consequently,' in this study the model of lP-ICSS/OD is analysed as the combination of lP ICMNCD and lP-CSSS/OD protocols. The new packet CDMA approach is evaluated in various  voice radio channels. A comparative evaluation of the competing access techniques and the novel  protocol are exercised with an example voice traffic model under multiple-access interference  assumption. The results demonstrate the throughput and delay performance in terms of the  number of active mobile terminals. Finally, These are used to identify the system offered capacity  while maintaining an acceptable voice performance. It is shown the capacity gain of lP-ICSS/OD  over the existing protocols in a DS/SSMA system
