Aiming at the problem of spectrum efficiency evaluation of radio systems in complex electromagnetic environment, a SUE evaluation method with environmental parameters is proposed to solve the problem of electromagnetic space occupation caused by complex electromagnetic environment and dynamic frequency assignment strategy. The simulation calculation example of SUE in mobile communication system is given. The results show that the calculated results are in good agreement with the experience and the computational process is feasible. By setting parameters such as M, Tw and Tc according to the specific system application and the electromagnetic environment complexity, the application of this method has good expansibility.
