Abstract :
In recent years, with the rapid development of the economy, people rely more and more on mobile communication, and therefore greatly promoted the rapid development of modern mobile communications industry, efficient mobile communication system has gradually become a new generation the direction of
development. This article describes the content of OFDM simulation and in mobile communications applications. This paper analyzes the principle of OFDM technology, establishes the simulation model of mobile communication system, writes the program code of the system, establishes the simulation model, analyzes
the interference factors in the process of the mobile communication transmission, and completes the analysis of the simulation result through simulation. This paper also focuses on the realization of orthogonal frequency division multiplexing (OFDM) and the performance of sub-channels and other parameters and reduces the peak-to-average power ratio of OFDM systems. Finally, the application status and prospect of OFDM technology in the modern communication system are expounded.
