Latest Patents

One of Böhnke's latest patents is focused on an optimized synchronization preamble structure. This proposal outlines a new synchronization (SYNCH) symbol sequence designed for transmission systems currently undergoing standardization. The synchronization symbol is constructed using specially designed OFDM (orthogonal frequency division multiplexing) symbols with an optimized sequence, which is mapped onto the modulated subcarriers. The resulting synchronization symbol consists of several repetitions in the time domain. By utilizing the proposed sequence, the synchronization symbol achieves high timing detection and frequency offset estimation accuracy. Additionally, the burst is optimized to ensure a very low envelope fluctuation, resulting in a low Peak-to-Average Power Ratio and a reduced dynamic range. This optimization minimizes complexity on the receiver and saves time and frequency acquisition time. Furthermore, the proposed sequence is refined concerning all other synchronization symbols used to construct the synchronization and training preambles for the BCCH-DLCHs.

Another notable patent by Böhnke is related to a transmission system for OFDM signals with optimized synchronization. This innovation further enhances the efficiency and reliability of transmission systems.
