A new national standard for Terrestrial Digital Multimedia Broadcasting (T-DMB) has been announced in Korea to provide high quality digital audio, video, and data broadcasting services to fired, mobile, and portable receivers. We have developed FPGMASIC implementation of the T-DMB system. This Paper describes the features and functions of the newly developed T-DMB system. Andwe also present the design, implementation. and performance of the baseband chip for the T-DMB system. The chip was fabiricated by using 0.25um lP4M CMOS process.Index Terms -Terrestrial DMB, DAB, OFDM,
