Method and arrangement for stabilizing a color coding method and optically transferring data

摘要

A method is provide for optically transferring data between a transmitter and a receiver employs a color coding method based on a plurality of elementary colors for encoding and transferring the data. Each elementary color is transmitted by one optical radiation source each on the transmitter side, and is received on the receiver side by one optical radiation receiver each. A control loop is formed between the transmitter and the receiver, wherein calibration messages are sent by the transmitter to the receiver, and wherein compensation information is determined by means of comparing at least one channel property of at least one received calibration message to a corresponding channel property of at least one previously transmitted calibration message, and wherein an adjustment of at least one transmitting parameter is made in the transmitter on the basis of the compensation information.

1. A method for optically transferring data between a transmitter and a receiver, comprising:
providing a color coding method based on a plurality of elementary colors for encoding and transferring the data, transmitting each elementary color by at least one respective optical radiation source on the transmitter side and receiving each elementary color on the receiver side by at least one respective optical radiation receiver, forming a control loop between the transmitter and the receiver, transmitting calibration messages from the transmitter to the receiver, determining by the receiver a compensation factor comprising or based on a number vector including diagonal elements of a compensation matrix determined from a channel property matrix of at least one received calibration message and a corresponding channel property matrix of at least one previously received or stored calibration message, based on the determined compensation factor, the receiver transmitting compensation information to the transmitter, and adjusting at least one transmitting parameter in the transmitter based on the determined compensation information.
