A Method for Inversion of Electrical Parameters of Materials Based on Ray Tracing Algorithm and Stochastic Gradient Descent Method

In wireless channel deterministic models, it is important part for the setting of environmental electrical parameters. Traditional calculation methods such as genetic algorithm and the ant colony algorithm are inefficient. This paper studies the stochastic gradient descent(SGD) algorithm to solve the electrical parameters. The simulation results show that the method based on ray tracing algorithm and SGD algorithm to solve the electrical parameters of materials is feasible and efficient.
