Code Division Multiple

 In this research paper the performance of the CDMA system has been analyzed with respect to PAPR (Peak to Average Power Ratio) measurement and its reduction. Simulation results verify that high peaks degrade the performance of CDMA, application of codes reduced high peaks and PAPR is a good measure for CDMA.

In this study, we consider zone-based registration (ZBR) in mobile communication networks. In ZBR, when a mobile moves to a new zone, it registers its zone to the network database to keep the mobile’s current zone, and to connect an incoming call to the mobile when it is generated. A mobile can store one zone, or more than one zones. Among various types of ZBR, we focus on two-zone-based registration (TZR), which is known to have good performance. In TZR, a mobile can store two zones that it has recently registered, and does not register when it crosses either zone that it has already kept. In general, in TZR, a mobile registers its zone less often than in single-zone-based registration (SZR). However, TZR increases the paging cost, because the network may not know the exact zone where the mobile is. Mathematical modeling and performance analysis are performed to obtain the exact performance of SZR and TZR, by considering the busy-line effect and implicit registration effect of outgoing calls from a mobile. From numerical results for various circumstances, it is shown that TZR is superior to SZR in most cases.
