Abstract :
DMB-T (terrestrial digital multimedia/television broadcasting), a DTTB (digital territorial television broadcasting) system based on TDS-OFDM (time domain synchronous orthogonal frequency division multiplexing), is introduced. TDS-OFDM employs time domain pilots for synchronization and channel estimation. Furthermore, the multiplex of guard intervals and time domain pilots to save bandwidth is explored
