Paired carrier multiplexing multiple-user access method

Abstract

The invention discloses a paired carrier multiplexing multiple-user access method comprising the following steps: arranging a network control carrier, a plurality of user access carriers and a plurality of service carriers in a very small aperture terminal (VSAT) satellite communication network, and allotting channels for a paired carrier multiple access (PCMA) user. The network control carrier comprises a time and frequency reference channel, a system state channel, a service distribution channel and a broadcast channel; each of the user access carriers comprises a user login application channel and a user response channel; each of the service carriers comprises a user communication service channel; each of the service carriers is divided into a plurality of time slots according to the time division multiple address (TDMA) mode; each of the time slots is a service frame; every 32 service frames form 1 super frame; and each of the super frames has a length of 320 ms. Before the channels are allotted for the PCMA user, the PCMA primary party logs in to apply for the channels, the network control center calls the PCMA secondary party, and the network control center allots the frequency and the time slots occupied by the signals of both the PCMA primary party and the PCMA secondary party and the logout indications of both the PCMA primary party and the PCMA secondary party if the PCMA secondary party responds to the network control center.

AI Technical Summary

Benefits of technology

This technology allows for multiple users (PCs) on different satellites to communicate with each other without interfering with one another's own signals or data transmission capabilities.

Problems solved by technology

Technological Problem: The technical problem addressed in this patents relates to enhancing efficient data transfer capabilities while reducing constraints associated with traditional systems like VST radios due to their large size and heavy weight. Current solutions involve adding extra components beyond just one component called an external device, making these techniques difficult to implement within current space limits without compromising performance levels.
