The Digital Terrestrial Television Broadcasting(DTTB)will start in 2000 in Japan. In the DTTB, the Orthogonal Frequency Division Multiplex(OFDM)is used. The OFDM is brand new technology, then many kind of in-door tests and verification tests in field are carried out to realize DTTB. But the time schedule was very tight, so some tests are omitted. To shorten the period of development, we have made a programmable signal processing system using CPU and Field Programmable Gate Array(FPGA)that controlled by Graphical Use Interface(GUI). In this paper the outline of the programmable signal processing system is mentioned, and some examples applied for the OFDM are also described.
