Title:
MODEL EVOLUTION-BASED ENVIRONMENT SENSING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/032009
Kind Code:
A1
Abstract:
The present invention discloses a model evolution-based environment sensing method. The method implements environment sensing by obtaining channel response data by periodically performing channel estimation tasks in existing communication systems. First, an interaction mechanism for electromagnetic waves and an environment target is divided into reflection and transmission; then a mathematical model for a channel response and the environment target is constructed, and an environment sensing problem is modeled into a compressed sensing optimization problem; finally, in order to solve the compressed sensing problem, a design of starting from a basic model and completing iteration and evolution of the model by solving for the target is implemented to finally achieve environment sensing. Compared with existing environment sensing reconstruction methods, the model considered in the present invention is closer to real electromagnetic wave propagation characteristics, has low requirement on environment prior information, remarkably improves the precision of environment sensing, and provides an effective method for achieving environment sensing in mobile communication systems.
