Research on Data Transmission Simulation System Based on Computer 3D Simulation Technology

This paper models the spatial distribution of communication node data in cellular heterogeneous networks based on computer three-dimensional simulation technology and using spatial Poisson point process. In this paper, the mathematical expectation, probability density function and cumulative distribution function of interference in the network are analyzed, and the cumulative distribution function of the signal-to-interference ratio of non-cellular communication nodes is derived. This paper configures different parameters for the cellular heterogeneous network that supports direct user communication and the cellular heterogeneous network that introduces small sites. The method compares the interference in two types of cellular heterogeneous networks under the premise of ensuring that the minimum signal power actually received by the user is equal. The paper verifies the correctness of the proposed analytical model and its derivation process through system-level simulation.
