Problems solved by technology

At present, in the field of mobile wireless communication (microwave band), because the frequency used is lower than that of optical communication, the transmission and reception methods are relatively limited. Considering the characteristics of large number of terminals and mobility, there are few researches on signal coverage methods.

Abstract

The embodiment of the invention discloses a system, a method and equipment for realizing signal coverage based on orbital angular momentum (OAM), and the system comprises a first modulation module which is used for loading data transmitted by a data channel of a local cell onto an OAM carrier for modulation; the second modulation module is used for loading data sent by a control channel of the cell to the OAM carrier for modulation; or the OAM carrier is used for loading data sent by the control channel of the cell to the non-OAM carrier for modulation. According to the technical scheme, the corresponding modulation modes are selected for the data sent by the data channel and the control channel, the situation that the data volume sent by the data channel is large usually, the channel capacity can be improved by using the OAM carrier for signal modulation, and the data volume sent by the control channel is small is considered, so that the control channel can adopt non-OAM carrier modulation, and the channel capacity can be improved. Certainly, OAM carrier modulation can also be adopted to realize OAM signal coverage in a mobile network area.

Description

technical field [0001] The present disclosure relates to the technical field, and in particular to a system, method and device for realizing signal coverage based on orbital angular momentum (OAM). Background technique [0002] Wireless communication based on Orbital Angular Momentum (OAM) is one of the hot topics in the field of communication recently. OAM waves have different vortex wavefronts, annular energy distribution, and strong directionality according to their angular quantum numbers. OAM waves with different angular quantum numbers (also known as different modes) have integral orthogonality. That is, different modes of OAM waves can transmit different information in the same frequency domain, the same time domain, and the same space, thereby greatly improving the capacity of the communication system. At present, in the field of mobile wireless communication (microwave band), because the frequency used is lower than that of optical communication, the transmission a...
