ABSTRACT:
Data encoded in packets modulated onto a carrier wave is transmitted between a base station and a transponder. Each packet includes a header section that contains at least a reference symbol and that serves for adjusting one or more transmission parameters, and a further section such as a data section. The transponder transmits data back to the base station through modulation and backscattering of the carrier wave. During the transmission of the header section by the base station, the transponder transmits transponder operating information relating to the processing of data to be received and/or transmitted by the transponder, by corresponding modulation and backscattering of the carrier wave. In response to and dependent on the received transponder operating information, the base station adjusts at least one transmission parameter, whereby the highest data transmission rate within the capabilities of the particular transponder can be achieved.
