| Popis: | In this paper, a novel localization algorithm is proposed by utilizing the time difference of arrival (TDOA) with asynchronous base stations. Generally, a TDOA-based localization algorithm requires synchronization between base stations. Hence, correlations using wideband signals or wire connections between base stations have been used to synchronize the base stations; however, these approaches result in localization error by synchronization error between base stations. Thus, the proposed algorithm does not require synchronization between base stations. The TDOA equations of proposed algorithm are derived by continuously varying the locations of the mobile station and the location of a base station. Localization procedure is also reduced. The localization performance of the proposed algorithm is verified with Monte-Carlo simulations. |
