Latest Patents
Langinieux's latest patents include an "Orthogonal frequency division multiplexing receiver system." This innovative OFDM receiver system is designed to perform precise OFDM demodulation. It achieves this by sharing memories and operators in a time-divisional manner. The system separates FFT-processed data into specific pilot signals and data based on timing indicated by a controller. This arrangement facilitates the extraction of corresponding pilot signals and data for various synchronization and equalization steps. As a result, the demodulation system can be optimized for resource utilization efficiency, reducing costs and time for fabrication and design.
Another significant patent is the "Frame synchronization method and apparatus for use in digital communication system utilizing OFDM method." This invention discloses a frame synchronization apparatus that includes a phase calculator for calculating phase values of TPS pilots within a symbol. It utilizes in-phase and quadrature-phase channel signals received from the transmitting side. The apparatus also features a D-BPSK demodulator for performing D-BPSK demodulation on the phase values of TPS pilots. This innovation allows for frame synchronization without increasing hardware size, enhancing the overall efficiency of digital communication systems.
