Abstract
This research is dedicated to the design and performance optimization of urban rail transit wireless communication systems,focusing on key aspects such as co-frequency interference,wireless signal coverage,and communication quality.Through in-depth requirements analysis,we propose network structures and optimization methods tailored to high-density,high-speed mobile scenarios.In the management of spectrum resources,advanced modulation and demodulation techniques,channel coding schemes,and Internet of Things technologies are introduced to enhance spectrum utilization efficiency.Simultaneously,effective measures are implemented to address co-frequency interference issues and optimize communication quality.In the design of antenna systems,we extensively discuss the selection and layout optimization of directional,omnidirectional,and combined antennas to adapt to the diverse scenarios of urban environments.The comprehensive solutions proposed aim to improve the performance of communication systems in urban rail transit,thereby promoting the sustainable development of intelligent transportation.
