Article Preview

This paper proposed a simple scheme for range measurement between the receiver and CTTB (Chinese Terrestrial Television Broadcasting) TV tower not depending on other aids. CTTB signals are used for range measurement and they are transmitted from CTTB TV tower. The scheme suits for any CTTB included positioning system. Simulated CTTB signals transmitted from CTTB TV tower are used to evaluate the performances of the proposed scheme. Simulations are done under both AWGN (additive white Gaussian noise) channels and real measured urban channels. And as a multipath fading exists in urban environment, we use a multipath rejection method to improve the range measurement accuracy. Our simulation results show that this range measurement scheme is effective in AWGN channels, and also in urban channels with the multipath rejection method. From the simulation results, we also know that the clock accuracy of the receiver affects the precision of this range measurement scheme.
