Optimized preamble and method for interference robust packet detection for telemetry applications

A receiver, comprising:

• a receiving unit configured to receive a data packet comprising a pilot sequence;
• and
• a synchronization unit configured to correlate the pilot sequence and a reference sequence, in order to acquire a correlation result;
• wherein the synchronization unit is configured to apply a weight factor to symbols of the data packet, or to apply a weight factor to symbols of the pilot sequence, or to apply an individual weight factor to each symbol of the pilot sequence;
• wherein the synchronization unit is configured to separately correlate the pilot sequence with at least two partial reference sequences, in order to obtain a partial correlation result for each of the at least two partial reference sequences;
• wherein the synchronization unit is configured to non-coherently add the partial correlation results in order to obtain a coarse correlation result for the data packet.

A method, comprising:

• receiving a data packet comprising a pilot sequence;
• and
• correlating the pilot sequence and a reference sequence, in order to obtain a correlation result;
• wherein a weight factor is applied to symbols of the data packet, or wherein a weight factor is applied to symbols of the pilot sequence, or wherein an individual weight factor is applied to each symbol of the pilot sequence;
• wherein the weight factor is obtained based on a determined signal-to-noise ratio;
• wherein an individual weight factor is applied to each symbol of the pilot sequence,
• wherein interfered symbols of the pilot sequence have lower weight factors, so these symbols have less influence on the correlation result.
