| 20100225852 | DISPERSIVE ELEMENT, DIFFRACTION GRATING, COLOR DISPLAY DEVICE, DEMULTIPLEXER, AND DIFFRACTION GRATING MANUFACTURE - In a transmission grating as a dispersive element, diffraction efficiency is enhanced and manufacturing costs are considerably reduced. A dispersive element includes resin members for forming a diffraction grating, being composed of a plurality of diffraction grating members having a cross-sectional shape respectively surrounded by two straight lines such as a triangular shape, and metal members as light-shielding members each being formed on corresponding one of the diffraction grating members at one side of the diffraction grating member along any of the straight line and the curved line of the cross-sectional shape of the diffraction grating member formed by the resin member. The metal members are configured to reduce zero-order transmitted light with respect to incident light, and to enhance diffraction efficiency of first-order transmitted light. | 09-09-2010 |

| 20090274221 | METHOD, HARDWARE PRODUCT, AND COMPUTER PROGRAM PRODUCT FOR PERFORMING HIGH DATA RATE WIRELESS TRANSMISSION - A method, a hardware product, and a computer program product for performing high data rate wireless transmission and reception. Minimum shift-keyed (MSK) data is transmitted by multiplexing a first MSK data stream and a second MSK data stream wherein the first MSK data stream is substantially 90-degree phase-shifted with respect to the second MSK data stream. The transmitted MSK data is received by performing phase recovery and demodulation using an FM discriminator having a demodulation circuit for implementing a 45-degree phase shift prior to demodulation. | 11-05-2009 |
| 20110130108 | RADIO RECEIVER, RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION METHOD, AND PROGRAM - A radio receiver including a sampling unit, a provider, an arithmetic operation unit, an estimator, and a converter. The sampling unit samples a baseband signal transmitted from the radio transmitter, at a fractional multiple of a symbol rate, and generates fractional-multiple-sampling data. The provider provides reference data in which the known symbol sequence arranged in a frame by the radio transmitter is interpolated at a rate of the fractional multiple. The arithmetic operation unit performs an arithmetic operation for evaluation data in which the degree of consistency in waveform between the fractional-multiple-sampling data and the reference data is evaluated. The estimator estimates a reference timing from a shift amount at which the evaluation data shows the maximum degree of consistency in waveform. The converter converts the fractional-multiple-sampling data by using the reference timing as a reference thereby recovering the data having the symbol rate. | 06-02-2011 |
