Abstract

The existing high frequency (HF) network frequency allocation uses fixed frequency point set, which is difficult to meet the demand of HF cognitive network dynamic spectrum access. According to the characteristics of HF frequency point fading, a HF frequency allocation method based on combination auction is proposed for HF cognitive network. Based on shortwave cognitive network characteristics, based on the short wave shortwave network, the paper designs combinatorial auction process of cognitive radio technology, builds the mathematical model of combinatorial auction to reduce time selective fading effect on the efficiency of the auction algorithm, introduced the gated recurrent unit (GRU) helped forecast model, realizing the frequency point during the week in predicting, improve the average buyer yields, increasing the efficiency of the frequency spectrum assignment. The simulation results show that the performance of the combinatorial auction algorithm increases with the improvement of spectrum sensing ability, and the average buyer's return rate increases significantly in the fading condition through frequency point state prediction. When the number of combinatorial frequency points increases, the link reliability is enhanced, but the average buyer's return rate decreases.
