20130315352 | COMMUNICATION APPARATUS - The present invention is directed to reduction of operation amount of likelihood calculation (LLR calculation) in a communication apparatus for performing communications using an extended mapping in which a plurality of bit sequences are assigned to a single symbol point. A receiving unit receives a signal which is transmitted from a transmitting unit by using the extended mapping. A repetition process unit decodes the received signal from the receiving unit by calculating an LLR of the received signal and performing a repetition process. In this case, the LLR is calculated for every bit using a MAX−LOG approximation and a thus-derived approximation formula is multiplied by weighting factors corresponding to proportions of “0” and “1” in each bit assigned to a symbol point closest to the received signal. | 2013-11-28 |

20130315360 | Rotating High Density Fusion Reactor for Aneutronic and Neutronic Fusion - A fusion device produces fusion of neutral atoms and ions in an “aneutronic fusion” manner without neutrons as products utilizes strong ion-neutral coupling at high neutral densities.

The repeated acceleration by strong magnetic forces in the azimuthal direction makes possible very high ion velocity. Fusion takes place mainly between neutral particles. This approach can be applied to fusion with neutrons as well. Conventional fusion schemes and neutron sources can be realized using the principles described above in the generation of neutrals of high energies and densities. | 2013-11-28 |

The error correction circuitry may also include a digital-to-analog converter (DAC) cooperating with the memory and coupled to the gain stage and capable of compensating for at least one error based upon the stored error compensation data. | 2013-11-28 |
