Wireless positioning approach using time delay estimates of multipath components |
摘要 |
<p>A wireless positioning apparatus (10, 30, 50) includes a multipath delay estimator (11) configured to estimate multipath delay components from one or more received signals; a selector (13, 53) configured to select appropriate delay estimates from the estimated multipath delay components according to a predetermined criterion; a storage (15, 55) configured to store an NLOS delay function defining prior (statistics of) information about non-line-of-sight delays; and a position estimator (17, 57) configured to estimate a position of a mobile station based on the selected delay estimates and the NLOS delay function read out from the storage.</p> |
