摘要： 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 X1 outputted from the IFFT unit into a complex signal X2 with a reduced peak factor based on subcarrier map information. The peak factor reduction unit generates a peak factor reduction signal by a linear combination of complex exponential functions that correspond to subcarrier frequencies to be used for wave transmission, as bases. The peak factor reduction signal is derived by repetition of, for example, a weighted least squares method or convolution processing by a fast Fourier transform.

摘要： 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).

摘要： It is an object of the present invention to reduce the amount of spurious noise generated by an emission line spectrum of a signal propagating around the PLL of a PLL frequency synthesizer carrying out digital-signal processing.In order to achieve the object described above, the present invention provides a PLL frequency synthesizer with the following configuration.In a PLL frequency synthesizer having a charge-pump circuit, a waveform converter is provided at a stage behind the charge-pump circuit. The waveform converter converts the voltage waveform on a time axis of a rectangular wave output by the charge-pump circuit into a waveform which: is symmetrical with respect to a predetermined point of time; oscillates so as to have no direct-current component; and has a maximum value of the absolute values of maximums of wave heights thereof located at the center wherein the absolute value decreases uniformly as the wave height is separated farther away from the center. As a result, the amplitudes of a limited number of emission line spectra forming a spurious signal superposed on a signal propagating around the PLL can be made uniform and a maximum thereof can be held at a low value, allowing the direct-current component to be eliminated from the signal propagating around the PLL.

摘要： In a portable telephone which uses a CPU, a memory, a temperature sensor, a D/A converter, and an A/d converter as control elements, and which has an oscillation circuit including a crystal resonator and a variable-capacitance diode, temperature compensation of the output frequency is made by using these existing control elements. The memory is previously stored with control information for correcting an output frequency drift of the portable telephone caused by a temperature change. The temperature of the oscillation circuit is detected with the temperature sensor and converted into a digital value in the A/D converter. The CPU reads control information corresponding to the detected temperature from the memory and applies it to the variable-capacitance diode of the oscillation circuit through the D/A converter, thereby maintaining the output frequency at a constant level. Also disclosed is a method of efficiently calculating an oscillation frequency of a crystal resonator with a reduced number of points of measurement for a temperature characteristic of the crystal resonator. A method of accurately carrying out the above-described temperature compensation is also disclosed.
