Power Optimization of CDMA based Tactical Networks

Wireless communication systems which employ multiple access techniques require very sensitive management of the sources. This is the key requirement because of random and frequent movement of mobile users and rapid variations in the channel. In Code Division Multiple Access (CDMA) based wireless communication systems, the most important issue on transmitter side is the power management. Intelligently controlled power heavily improves the systems performance and capacity. The requirement of power control becomes more important in tactical network which is a type of self organizing and self operating systems. The aim of this research work is to optimize the transmitted powers of mobile users in a multiuser CDMA based tactical networks. The proposed power optimization method for tactical networks is of valuable importance because it can be extended to other types of networks which are self organizing and infrastructureless. This work deals with the power optimization of multiple users of CDMA system where only peer-to-peer communication can take place due to the absence of any central unit or base station.
