A large amount of complex calculation will be performed when complex finite impulse response filter is applied to filter complex signal.Therefore,its construction is more complex than a real number filter.In the paper,a new scheme is presented,which combines DSP Builder with EDA Tools and optimizes the construction of complex filter.It is implemented with FPGA.Compared with other schemes,this scheme has the advantage that simulation and design can be conducted simultaneously without consideration of the circuit and modeling for the filter.As a result,the difficulties in the design are greatly reduced and the design period is shortened.
