Title: Innovations of Andreas Leven in Amplitude Modulation
Introduction
Andreas Leven is a notable inventor based in Bietigheim Bissingen, Germany. He has made significant contributions to the field of amplitude modulation, particularly in the area of bits-to-symbols mapping. His innovative work has implications for various communication technologies.
Latest Patents
Andreas Leven holds a patent for "Bits-to-symbols mapping for amplitude modulation." This patent focuses on architectures for inter-converting bitstreams and symbol streams of Pulse Amplitude Modulation (PAM) and/or Quadrature Amplitude Modulation (QAM) constellations of different sizes that are not base-2 integers. Some of these constellations may be Gray-coded, and the mapping aims to achieve an equiprobable distribution of different constellation symbols. The invention includes embodiments that may be compatible with Forward Error Correction (FEC) schemes. In one example, a transmitter Digital Signal Processor (DSP) may utilize a conventional constellation mapper preceded by an electronic encoder programmed to exclude certain constellation-symbol labels from the bitstream applied to the mapper. The electronic encoder may employ a Constellation Code Division Multiplexing (CCDM) and/or a long-division operation to select specific amplitudes of the constellation while excluding others. This innovative approach is beneficially capable of achieving a smaller gap to the Shannon limit compared to conventional solutions.
