Data Exchange of Relay Transmission and Information Scheduling in Shared Networks

Abstract

With the diversification of the kinds of wireless transmission service, the transmission rate and reliability of wireless communication have been demanded sharply. The shortage of resources of spectrum has become continuously prominent. These are bottlenecks to restrict the development of wireless communication. The current multi-antenna cooperative relay communication system can't sense complex communication scenes agilely, and adjust the strategy of interference suppression according to the signal characteristics adaptively, and optimize the resource of the system dynamically. Moreover, the degree of freedom and transmission system reliability should have been further improved. Aiming at the above problems, this paper extracts the features of the combined signal from different degrees of freedom, considering the influence and effect of the distribution characteristics of the signal on its separability, and signal spatial structure to enhance the ability to adapt to complex environmental interference. It explores multiple interactive cooperative transmission scheduling to optimize the wireless resource dispatching and new network coding jointly, and get a unified multi antenna relay transmission processing standards and to improve the efficiency of information transmission. It carries out theoretical studies of interference coordination algorithms which can acquire higher forwarding efficiency at relay in the view of energy efficiency and spectral efficiency.
