Optimized Preamble and Method for Interference Robust Packet Detection for Telemetry Applications

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes an improved method for detecting data packets in telemetry systems by optimizing the process of synchronizing and identifying packets, even in the presence of interference. The receiver uses a technique that divides a known pilot signal into several segments, correlates these with reference sequences, and then combines the results to achieve robust packet detection.

Patent Abstract

To provide a receiver having a receiving unit and a synchronization unit.SOLUTION: In the receiver, the receiving unit receives a data packet having a pilot sequence. The synchronization unit separately correlates the pilot sequence with at least two partial reference sequences corresponding to a reference sequence for the pilot sequence of the data packet, in order to obtain a partial correlation result for each of the at least two partial reference sequences, and non-coherently adds the partial correlation results in order to obtain a coarse correlation result for the data packet.SELECTED DRAWING: Figure 1
