METHOD AND APPARATUS FOR ENHANCING SIGNAL-TO-NOISE RATIO OF POSITION LOCATION MEASUREMENTS |
摘要 |
For generating and use of a position location reference signal that allows a receiver to receive position location signals from relatively weak signal generators when in the presence of a strong signal source, near-far problem. The position location reference signals from multiple sources can be synchronized to be transmitted within a scheduled time slot during which signal source can configure a transmission that includes a media access control address that corresponds to a value reserved for position location signals. Each signal source also configures the transmission to include a position location reference signal that corresponds to the signal source which is positioned to occur at a time within the data portion of the scheduled time slot, which has a plurality of sub-slots and each source will send a position location signal in a sub-slot and will not send in the others.
