OFDM as the MCM is one of the key technologies for the 4G mobile communication. To implement the OFDM signal by hardware, we usually use the DSP device to finish IFFT process. In order to save hardware resource, reduce cost and be suitable to realize adjustment of the frequency, amplitude and phase for the OFDM signal, the paper refers to the 192 sub-carrier number in DAB mode 3, firstly produces the ideal OFDM signal wave as the test standard by computer program, then adopts MCU and look-up table approach to implement a programmable OFDM signal generator. The test result show that the generator works well and the frequency, amplitude and phase can be adjusted.
