Hardware Design of Software Radio Receiver Based on FPGA

To achieve various functions of communication system by software as far as possible,reduce the cost of design,prove the processing of the system,solve the bottleneck problem of DSP in software radio,the design is based on FPGA to build a hardware processing platform of software radio receiver.The design has completed the functions of A/D converter,digital down conversion,digital signal processing and so on.The design receives the functional simulation result of QPSK,which is used in communication system.The results certify that this design is correct.The system not only improves the flexibility and re-configurability,but also reduces the cost.
