Abstract	Digital Intermediate Frequency (IF) technology is widely used in wireless communication system in recent years. This paper introduces a digital IF module, which is applied to a Broadband Wireless Ad hoc Network (BWANET) system. IF module contains Digital Down Conversion (DDC) and Digital Up Conversion (DUC), filter design is one of its key technologies. The design of IF filter is based on technology of multi-rate signal processing, interpolation filter performs up-sampling of the data, while decimation filter finishes down-sampling of the data. After a comparative analysis, this paper presents an IF filter structure which requires minimum hardware resource usage. Hardware co-simulation, which is a new simulation method, is adopted for functional simulation in this paper; it greatly reduces the simulation time. The results of the hardware co-simulation and experiment show that the IF module operates normally and has a good performance index.
