摘要：
In a communication system, the effective degree of freedom (DoF) has a limit with the increasing of the number of sources/receivers. In this paper, the parabolic equation method is used to establish the electromagnetic (EM) channel model. And the correctness of the model is verified by comparison with the free space analytical solution. In addition, the sensitivity between the size of the transmitting surface and the effective degree of freedom is analyzed by using parabola method. The channel matrix model based on the parabolic algorithm provides a reference for establishing efficient and stable communication lines in free space.
