5G SLAM Using the Clustering and Assignment Approach with Diffuse Multipath.
Sensors (Basel)
August 2020
Article Synopsis
- 5G systems above 24 GHz show potential for improving user localization and environment mapping, but existing methods have limitations.
- This study introduces a four-phase model that includes downlink data transmission, channel estimation, clustering parameters, and simultaneous localization and mapping (SLAM) using a new likelihood function.
- The proposed method simplifies the process, reducing complexity and addressing real-world challenges, with simulations indicating its effectiveness.
Future intelligent transport systems depend on the accurate positioning of multiple targets in the road scene, including vehicles and all other moving or static elements. The existing self-positioning capability of individual vehicles remains insufficient. Also, bottlenecks in developing on-board perception systems stymie further improvements in the precision and integrity of positioning targets.

Multiple sensors are placed at different locations to ensure that the backscattered signal could be detected by at least one sensor no matter which direction the human subject faces. We design a hidden Markov model to infer the subject facing direction and his or her chest movement.
