Application of Paired Carrier Multiple Access Technology in Range Satellite Communication System
Satellite communication has the advantages of wide coverage,convenient deployment and free from geographical restrictions,and is an important part of the range information communication system.However,due to the limited resources of satellite transponder and the difficulty of communication support,there are some limitations in the application of satellite communication system.By applying Paired Carrier Multiple Access(PCMA)technology based on correlation function to the range satellite communication system,the communication parties are enabled to work in the same frequency band by PCMA equipment,thus the satellite transponder resources are saved nearly half,the requirements of satellite communication support are met.And the proposed method has good self-interference suppression ability,can effectively improve the performance of the range satellite communication system.
