System for synthesizing signal of user equipment and method thereof

A system for synthesizing signal of user equipment, comprising:

• a physical channel modeler configured to receive geographic information of a field under test and a sparse real physical field channel feature, to build a physical channel model and estimate a plurality of predefined positions of the geographic information by using the physical channel model, to obtain a plurality of simulated physical field channel features corresponding to the plurality of predefined positions, wherein the sparse real physical field channel feature comprises a plurality of real physical field channel features measured at a plurality of measure positions of the geographic information, respectively;
• and
• a physical channel training module connected to the physical channel modeler, and configured to receive the geographic information, the sparse real physical field channel feature and the simulated physical field channel feature, and perform training on the geographic information, the sparse real physical field channel feature and the simulated physical field channel feature by using an artificial intelligence algorithm, to perform an inference of fully real physical field channel feature covering the plurality of predefined positions and the plurality of measure positions.
