Abstract |
In the 3rd generation (3G) telecommunication, the subscriber radio techniques based on time difference of arrival (TDOA) became one of the key technologies. Chan-Ho is a method that is widely used in solving the TDOA hyperbolic equations, but its performance is highly dependent on the pure distance term between the home base transceiver station (BTS) and the mobile handset. The proposed procedure uses another term that will utilize the relation between the mobile handset with two base transceiver stations. The performance of the proposed algorithm and the original Chan-Ho algorithm are evaluated and the simulation results show that the proposed algorithm has the advantage over the original |
