DATA DISSEMINATION IN A NAVIGATION OR COMMUNICATION SYSTEM

摘要

This relates to a method for disseminating data in a navigation or communication system comprising several transmitters for signals, wherein a common frame structure is provided for the signals and each transmitter disseminates common data and transmitter-dedicated data with its transmitted signal, and wherein the method comprises the following acts to be executed by each one of the transmitters: receiving the common data encoded with a first encoding scheme; encoding transmitter-dedicated data onboard the transmitter with a second encoding scheme; assigning the encoded common data to a number of first frames of the frame structure provided for the signals and assigning the encoded transmitter-dedicated data to a number of second frames of the frame structure provided for the signals, wherein the second frames differ from the first frames; assembling a signal to be transmitted from the number of first and second frames; and transmitting the assembled signal.

1. A method for disseminating data in a navigation or communication system comprising several transmitters for signals, wherein a common frame structure is provided for the signals and each transmitter disseminates common data and transmitter-dedicated data through its broadcasted signal, and wherein the method comprises the following steps to be executed by each one of the transmitters:
receiving the common data encoded with a first encoding scheme; encoding transmitter-dedicated data onboard the transmitter with a second encoding scheme; assigning the encoded common data to a number of first frames of the frame structure provided for the signals and assigning the encoded transmitter-dedicated data to a number of second frames of the frame structure provided for the signals, wherein the second frames differ from the first frames; assembling a signal to be transmitted from the number of first and second frames; and transmitting the assembled signal.
