The paper mainly discusses the design of base-band of UWB transmitter.The design is accomplished by employing FPGA and Verilog HDL.And a new Base-4 algorithm is adopted to proceed 128 bit FFT which only needs 4 Fourier matrix.It can reduce the complexity of system design and the number of the multiplication units in the chip.Eventually,the emulation of the design is introduced.
