Abstract

Synchronization of a Wireless Sensor Network is a crucial task and is based on a precise syntonization of all clocks within the network. The synchronization precision is usually closely connected to the positioning accuracy in networks for the purpose of localization. This paper introduces a concept, how the clocks of low-complexity stationary receivers can be adjusted to the same frequency with the help of a television broadcast signal. Only parts of the signal information are used to achieve a manageable data rate for the embedded low-power processor. With a new algorithm the performance of the frequency estimation can be kept high compared to the use of the total signal energy, while the processing load can be reduced dramatically.
