Abstract :
In this paper the implementation of a multirate QPSK modulator is presented. The modulator architecture has been optimized to reduce the hardware complexity and maximize the carrier frequency in order to meet the requirements of deep space and satellite applications. Finally, the performance has been evaluated by implementing the modulator on a Xilinx XC2V3000 FPGA
