Optimization Method of OFDM Shared Signal Frequency Resource Based on Complexity of Electromagnetic Environment

Aiming at the typical OFDM shared signal, a method of frequency resource optimization based on the complexity of electromagnetic environment is proposed. Firstly, the mathematical model of multi-dimensional electromagnetic environment occupancy in time domain, spatial domain and frequency domain is given. Based on the above model, a method of adaptive allocation of sub-carriers in different frequency bands is given. It has a pioneering significance in the optimization of integrated frequency resources of radar communication and jamming.
