摘要
Abstract
In this paper, a design of all digital receiver based on software defined radio is presented. The signal is sampled on intermediate frequency in the receiver. The paper introduces the key technologies of this receiver such as band-pass sampling theorem, digital down-conversion and demodulation. The structure of multiple steps of filtering and decimation is adopted in DDC, and the detailed implementation of CIC, HB and FIR is given. The design is used in a FPGA platform with a CPCI bus interface. Demodulation of MPSK and 16QAM is achieved. The system has good extensibility and flexibility.关键词
