20080219372 | OFDM MODULATOR - An OFDM modulator having a peak factor reduction function. The OFDM modulator has a peak factor reduction unit between an IFFT unit and a guard interval insertion unit thereof. The peak factor reduction unit converts a complex signal X | 09-11-2008 |
20100046359 | Wireless Terminal, Base Station and Channel Characteristic Estimating Method - In a wireless communication system based on an OFDM access system, when forgetting averaging channel estimation is performed, there occurs a phase difference between a present channel estimated value and a past estimated value due to a change of FFT operation timing at a reception side. The error of the channel estimated value caused by the phase difference is corrected. A synchronization catching/tracking unit to determine an operation timing of an FFT from a received signal is provided, and an FFT operation timing difference acquisition section to grasp a change of the operation timing of the FFT generated by the synchronization catching/tracking unit is provided. Based on an FFT operation timing change amount as an output of the FFT operation timing difference acquisition section, a rotation operation is performed on a propagation path estimated result stored in a channel estimation section to estimate a propagation path from a received pilot signal, so that the error of the channel estimated value is corrected. | 02-25-2010 |
20110096865 | Digital predistortion transmitter - There is a need for effectively compensating distortion when a predistortion transmitter is subject to not only a memory effect due to nonlinearity of an amplifier, but also a modulator's DC offset, IQ unbalance, or local quadrature error. A predistortor to be used is a polynomial predistortor including a polynomial basis generation portion and an inner product calculation portion. The polynomial basis generation portion delays a real part and an imaginary part of a complex input signal Sx=Ix+jQx for up to M samples to generate 2(M+1) signals, duplicately combines these signals to generate monomials having maximum degree N, and outputs, as a basis vector, all or part of the monomials depending or needs. The inner product calculation portion performs an inner product calculation using a coefficient vector, i.e., a set of complex numbers sized equally to the basis vector to find a polynomial value and outputs the value as a complex signal. | 04-28-2011 |

20080254536 | Method of elevating photosynthesis speed of plant by improving pyruvate phosphate dikinase - The present invention relates to the transformation of C4 plants. It also relates to the high-level expression of foreign genes in C4 plants. More specifically, the present invention relates to the creation of C4 plants retaining an excellent photosynthetic capacity at low temperature by achieving high-level expression of an enzyme constituting the C4 photosynthetic pathway. In the present invention, C4 plants are transformed using an expression cassette that comprises a promoter, a C4 plant genomic gene, under control of said promoter, encoding an enzyme constituting a photosynthetic pathway, and a terminator. The C4 plant genomic gene encoding an enzyme constituting a photosynthetic pathway is preferably a C4 plant genome-derived PPDK gene or a modified form thereof. The present invention is particularly useful in improving the production of C4 plants having PPDK (especially, in improving the production of maize under low temperature conditions). | 10-16-2008 |

20110046352 | DISEASE-RESISTANT PLANTS AND METHOD OF CONSTRUCTING THE SAME - The present invention provides transgenic, disease-resistant plants which have been transformed with an expression cassette including a constitutive gene expression promoter; and a gene, under the control of the promoter, encoding a harpin. The transformed cells in the transgenic plant effect the constitutive expression of the harpin in an amount effective for inducing a defense reaction. The harpin is a protein consisting of an amino acid sequence that is at least 90% homologous to the amino acid sequence of SEQ ID NO: 2, and possesses a hypersensitive-response-inducing activity. The present invention also provides methods for producing the transgenic plants, expression cassettes, recombinant vectors and genes encoding harpins. | 02-24-2011 |
