Claim Text:
1. A device for determining an encoded data sequence as a determined data sequence, the encoded data sequence being encoded by an input signal frequency-modulated in accordance with a modulation rule, the encoded data sequence comprising a plurality of data elements, comprising: a filter unit for filtering the frequency-modulated input signal in order to acquire a first frequency-filtered channel signal and a second frequency-filtered channel signal, an evaluation unit configured to associate two channel-specific signal-to-noise distance values to each data sequence of a set of known data sequences, wherein the evaluation unit is configured to determine, for each data sequence of the set of known data sequences, a first channel-specific signal-to-noise distance value of the two channel-specific signal-to-noise distance values based on said data sequence and based on the first frequency-filtered channel signal, and wherein the evaluation unit is configured to associate said first channel-specific signal-to-noise distance value of the two-channel-specific distance values to said data sequence, wherein the evaluation unit is configured to determine, for each data sequence of the set of known data sequences, a second channel-specific signal-to-noise distance value of the two channel-specific signal-to-noise distance values based on said data sequence and based on the second frequency-filtered channel signal, and wherein the evaluation unit is configured to associate said second channel-specific signal-to-noise distance value of the two-channel-specific distance values to said data sequence, and wherein the evaluation unit is configured to select from the set of known data sequences a data sequence as the determined data sequence that has an associated channel-specific signal-to-noise distance value which is greater than another channel-specific signal-to-noise distance value associated to another one of the known data sequences.
