Abstract: A clipping rate is controlled in spectrum shaping according to a propagation path to thereby improve transmission characteristics and perform communication at a stable transmission rate.
Propagation path characteristics are detected by a propagation path information detection unit 5 for detecting propagation path information fed back from a base station device and a water filling principle for distributing energy by a primary spectrum shaping unit 6 according to the propagation path characteristics is applied to transmission spectrum obtained by a DFT unit 4. Clipping information in secondary spectrum shaping fed back from the base station device is detected by a clipping information detection unit 7 to perform the secondary spectrum shaping by a secondary spectrum shaping unit 8. At this time, with the clipping rate by the secondary spectrum shaping unit 8, clipping rates of all transmission devices multiplexed in a scheduling unit 26 of the base station device are controlled adaptively.

Abstract: A fluorescence microscope in which spatial resolution is enhanced by performing observation based on the saturation component of fluorescence. The fluorescence microscope comprises a light source (10) emitting laser light to serve as pumping light, an objective lens (13) for focusing the laser light and irradiating a sample with the focused laser light, a detector (22) for detecting fluorescence generated from the sample (14) by the laser light, and a stage (15) performing scanning while varying the relative position of the laser light and the sample (14). The sample is irradiated with laser light while varying the intensity of the laser light such that the fluorescence saturates when the intensity of laser light is the greatest, the fluorescence depending on the intensity of laser light is detected by the detector (22), and observation is performed based on the saturation component of fluorescence.

Abstract: A wireless communication system includes: a multiple number of mobile station apparatuses that transmit coded bits obtained by applying error-correction coding to information bits; a relay station apparatus that receives coded bits from the multiple mobile station apparatuses, applies network coding on the coded bits and transmits the network-coded bits; and a base station apparatus that receives and decodes the codedbits and the network-codedbits, wherein the base station apparatus, when decoding the received coded bits, performs iterative decoding by regarding the received coded bits as a serially concatenated code of network coding and error correction coding. Accordingly, decoding is performed by regarding the network code and the error correction code as a serial concatenated code, it is possible to obtain diversity with a simple configuration. Further, since no lamination is imposed on the error correction codingmethod, it is possible to provide a wireless communication system and the like which allow flexible system design.
