Distributed Antenna Systems (DAS) are gaining widespread popularity in the indoor wireless market. Most of the existing research literature on this subject has focused on comparing the advantages of DAS systems with traditional macro cells. The goal of this thesis is to define a performance platform for CDMA based distributed antenna systems which can serve as essential design guidelines for future DAS deployments. One of the major issues presented by DAS systems is the noise floor rise in the reverse link caused by the DAS noise figure. This noise rise becomes a limiting factor in determining capacity and coverage of the DAS based network. The common practice of adding an attenuator (padding) in front of the Base Station receiver can bring down the noise floor, but at the same time force the mobile units to transmit at higher power. We establish an operating platform for the DAS so that the system can be effectively operated within the limits of mobile transmit power and base station receive power, maximizing the system capacity.
