Abstract
Transmitter identi¯cation (TxID) tech-
nique is used to diagnose the operating status of radio
transmitters in DTV distributed transmission network. In
this paper, a new kind of TxID method for DVB-H system
is proposed. A steganography signal (e:g. watermark) is
embedded in the DVB-H signal to form the composite sig-
nal. By watermarking theory, we demonstrate the required
signal level for watermarking signal to achieve a given bit
error probability in di®erent circumstances. By selecting
the reference pattern to generate the watermarking signal,
Peak-to-average power ratio (PAPR) of the transmitted
signal can be improved. Simulation results show that dis-
tortion to the host signal can be ignored, and the receiver
can distinguish the watermarking signal with low embed-
ding strength even in wireless situation.
