| Abstract: | The general design of digital receiver in intermediate frequency is presented. The design conception and method are introduced in conjunction with the theory and method of software radio. The concrete implementation procedure is demonstrated thoroughly. The application of A/D and FPGA highly increases the final processing speed of this system with high integration, good reliability and flexibility. So it possesses reference value in various applications. |
