Abstract

Cognitive radio (CR) is a revolutionary technology of wireless mobile communication. Smart users can use the CR technology to sense the surrounding environment, search for available spectrum resources and access spectrum dynamically. Differential frequency hopping (DFH) was believed to be an effective FH technique for increasing data rate of HF communication system. The cognitive radio technology is introduced in DFH. And a cognitive radio based multiple access algorithm (ITMA) is proposed. This algorithm is based on the interference temperature model, which is applied to the DHF network with the MAI-tolerant. The scenario simulations of the ITMA DFH network and the conventional DFH network are performed, respectively. The results show that the ITMA DFH network can obtain favorable network performance.
