A satellite, the mobile terminal and a component of the earth in a system multi-beam satellite based on an ofdm multiplexer, and advantages of the corresponding communication

摘要

It is proposed a method of communication of a mobile terminal (400) in a system multi-beam satellite based on an orthogonal frequency division multiplexing (ofdm) uses the same frequency band for all the beams, the method comprising the steps consisting in: receive information from the position of the mobile terminal (400) coming from a satellite (410) in order to determine a position of the mobile terminal (400) to the inside of the multiple beams, to determine a group of under - carriers for a communication with the satellite (410) as a function of the position of the mobile terminal (400) in the multiple beams, and communicate with the satellite (410) using the group of under - carriers for communication with the satellite (410).
