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

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 correlation window is used for detecting the data packet, wherein the data packet is detected by detecting the highest peak of all correlation peaks exceeding a predefined threshold within the correlation window;
• wherein the correlation window is divided into a plurality of time slots, each time slot having an index associated therewith;
• wherein if a correlation value above the predefined threshold is detected, a highest peak inside the correlation window is searched, wherein the data packet detection is blocked until the index of the highest correlation peak inside the detection window reaches a defined detection index.
