Design of digital wireless transceiver system

The wireless transceiver system design process is introduced.The system is used digital intermediate frequency technology in FPGA,the transmitter adopts FM modulation to deal with signal while the receiver use the DDC and the undersampling technique to sample and demodulation the IF signal for restore the original signal.The system is designed by building blocks,the function and the realization of each module circuit have been stated,making it flexible and structuring to realize.The circuit is designed and finished in Protel99,which also has been programmed and simulated with digital intermediate frequency by VerilogHDL.The system has been realized and can send or receive signal successfully.Proved to meet requirements raised by designer.
