Multi-Link Wireless Positioning Terminal Trajectory Matching

The patent segments the signal reception process by utilizing multiple communication links (direct wave and reflected wave paths) to receive the same signal from the base station. Each link provides independent RSSI measurements, which are then combined to create a more robust matching criterion. This segmentation allows the system to achieve accurate matching without requiring excessively long intervals, as the multiple links provide redundant information that improves matching reliability within shorter time frames.

The patent merges the RSSI measurements from multiple communication links (direct wave path and reflected wave path) into a combined matching criterion. By combining the information from multiple links, the system achieves more reliable and distinctive trajectory features that can withstand higher threshold values while maintaining successful matching rates. The merged information from multiple links provides a more robust basis for matching that is less susceptible to environmental variations.

The patent makes the wireless positioning terminal multi-functional by enabling it to receive and process signals through multiple communication links simultaneously. The same wireless receiver is utilized to capture both direct wave and reflected wave signals, making the device capable of performing enhanced positioning accuracy without requiring additional specialized hardware. This multi-functionality allows the system to achieve high positioning accuracy while maintaining relatively simple device architecture.
