Abstract :
A new frame structure based on time-domain synchronous orthogonal frequency division multiplexing for digital terrestrial television broadcasting (DTTB) uplink systems is proposed, whereby multicarrier pseudonoise (PNMC) training sequences are used as the frame header (FH). Sub-sequences of FH are inserted between signal frames as guard intervals. Simple multi-user channel estimation and equalisation can be applied and good performance is illustrated by simulations.
