A design and realization of high efficiency digital up conversion on multi-standard short-wave radio software radio is introduced in the paper. Combined Matlab turning filter parameters, the system model is built in quartus II and simulated in modelsim, the result of simulation indicates that high efficiency digital up conversion based on FPGA satisfies the performance requirements of standard short-wave radio and reduces hardware resource consumption. The design is characteristic of flexibility, universality and easy parameter modification.
