全雙工無線網(wǎng)絡的容量分析
[Abstract]:In recent years, due to the rapid growth of wireless network users, wireless network spectrum resources are increasingly scarce, which can not meet the growing needs of wireless network users. Therefore, how to further improve the spectrum efficiency of wireless networks and further optimize the network capacity are more and more challenging when the spectrum resources are limited. Full duplex technology can receive and transmit wireless network signals at the same time, which can increase the network capacity exponentially. Therefore, full duplex technology has great attraction for wireless network researchers. Although in theory full-duplex technology can increase the network capacity twice as much as half-duplex technology, in practice, due to the existence of self-interference, the capacity gain of full-duplex technology is often not equal to the theoretical one. Even when the self-interference is too strong, the decoding efficiency of full-duplex node is reduced, and its capacity is even lower than that of half-duplex wireless network. Many studies on self-interference elimination techniques, although to a large extent eliminating self-interference, are still unable to achieve complete elimination, The residual self-interference caused by the elimination of incomplete self-interference often affects the capacity gain of full-duplex technology, which makes researchers unable to accurately understand the capacity problem of full-duplex wireless networks. Even under the assumption that self-interference can be completely eliminated, many researchers have studied the capacity of full-duplex wireless networks, which is obviously not realistic. In this paper, different from previous studies, we improve the successful transmission probability model used in the past and calculate the successful transmission probability of full-duplex wireless networks using the signal-to-interference ratio (SIR) model. Our research shows that under the premise of bidirectional successful transmission in some links, there is still a possibility for other links to realize one-way successful transmission, and these one-way successful transmission links are often ignored in the past studies. These neglected one-way successful links improve the transmission probability and network capacity of full-duplex wireless networks and reflect the capacity gain of full-duplex wireless networks. In Chapter 3, we use Poisson Point process to simulate wireless network. According to the randomness of node distribution in wireless ad hoc network, it is easy to lead to interruption, and the use of full-duplex technology will increase the number of interference nodes and increase the interference of wireless network. We apply full-duplex technology to the interrupt constraint model, and give an interrupt constraint under the premise of given an interrupt constraint, because of its own characteristics of self-interference problem, such as increasing the outage probability, and so on, in this paper, we apply the full-duplex technique to the interrupt constraint model. The range of Poisson point process density under the condition of the interrupt constraint is calculated, and the transmission capacity of the full-duplex wireless ad hoc network is calculated under the condition that the interruption constraint is satisfied. Our research improves the transmission probability of full duplex wireless network and optimizes the capacity of full duplex wireless network.
