Study on Dynamic Allocation technology of Electromagnetic Frequency Spectrum under Regionalized Supplying Condition

摘要

Dynamic management of electromagnetic frequency spectrum is important to realize military regionalized supplying. In this paper, application characteristics of OFDM is firstly introduced, then OFDM system resource allocation ways and models are illustrated, and finally, typical RA subcarrier allocation algorithms are put forward, which provide theoretical reference for choosing dynamic allocation technology of electromagnetic frequency spectrum.
