Code Division Multiple Access (CDMA) has become the technology of choice for the current and future generation of wireless systems. We have implemented the CDMA IS-95 based Wireless Transceiver System using Matlab Simulink v 7.0. The entire system is implemented using the Xilinx System Generator Block v6.3. Even though the CDMA IS-95 system is already implemented in Simulink and is provided as a demo, there is no way of converting it into real Hardware. Using Xilinx System Generator we have made our implementation capable of being translated into any of the HDL codes. This can be then mapped onto appropriate FPGA easily. We have used the hardware co-simulation feature of the Xilinx System generator to create a library of the basic building blocks of the IS-95 system. This library can be used for implementing to create the various channels that are the part of the CDMA system.
