This paper explores real-time modeling and simulation of communication systems based on an enhanced discontinuous Galerkin time-domain (DGTD) method. Real-time simulation of communication systems is of significant importance in network design and optimization, as well as in the evaluation of attack defense strategies. Traditional simulation methods often suffer from low computational efficiency and long response times when handling large-scale communication networks, failing to meet the demands of real-time simulation. To address this, the paper proposes an improved DGTD method, which incorporates matrix reuse techniques and a time series prediction approach based on long short-term memory (LSTM) networks. These enhancements significantly boost the computational efficiency and real-time performance of the simulation. By thoroughly exploiting the periodic/quasi-periodic characteristics of the simulation model to reduce memory consumption, and by employing the LSTM-based time series prediction method to minimize the number of time integration steps, the overall time consumption is markedly reduced. The paper showcases the effectiveness of the enhanced DGTD method in simulating wireless communication networks through practical application cases. Experimental results demonstrate that the improved DGTD method can efficiently simulate signal propagation performance and provide real-time simulation feedback. With further algorithm optimization and enhanced utilization of computational resources, the improved DGTD method holds extensive application prospects and significant research value in the realm of real-time communication simulation.
