摘要:
Inter-carrier interference caused by frequency fluctuations, amplitude fluctuations, phase fluctuations, or the like is reduced without reducing a transmission efficiency. A receiving end has a canceling filter section that alleviates the inter-carrier interference caused by the frequency fluctuations, the amplitude fluctuations, the phase fluctuations, or the like through filtering processing. A transmitting end has a precoding section that facilitates determination of demodulation data in a vector demodulation section on the receiving end through precoding processing. Or, the receiving end has a trellis decoding section that decodes the demodulation data through trellis decoding processing.

An object is to generate a pilot signal for estimating transmission characteristic of a transmission channel which is suitable for the OFDM/OQAM multicarrier modulation. A phase reference pilot symbol of which a modulation amplitude is suppressed to zero, and an amplitude reference pilot signal obtained through modulation performed by using an amplitude known to a reception end are transmitted from a transmission end, and the transmission characteristic of the transmission channel is estimated and compensated by using the phase reference pilot signal and the amplitude reference pilot signal at the reception end. Thus, it is possible to simplify frame generation process performed at the transmission end, and reduce transmission power for the phase reference pilot signal.
摘要:
In a transmitter, at least one pilot carrier which is modulated with a signal sequence including a reference pilot signal sequence represented by any of amplitude modulation vectors {α, α, −α, −α}, {α, −α, −α, α}, {−α, α, α, −α}, and {−α, −α, α, α} where α represents a real number other than 0, is generated, and an OFDM/OQAM multicarrier modulation signal is transmitted. In a receiver, the OFDM/OQAM multicarrier modulation signal is demodulated, and transmission channel characteristics are estimated and corrected based on two successive demodulation vectors in a time direction which are obtained by demodulating the pilot carrier.

A document capture system may automatically capture documents and/or financial information for a user. The document capture system may capture and save documents a user views in a web browser. A user may visit various web sites to view financial data and a document capture plug-in module installed in the web browser may capture or save the viewed document. The document capture system may capture financial data while the user is visiting web sites normally—that is, not just when the user if visiting them particularly to collect financial data. The document capture system may be configured to automatically detect when the user views certain documents and may be configured to continually monitor the user's web activity in order to capture financial documents whenever the user visits certain sites. The document capture system may include a list of URLs representing web sites or documents that should be automatically captured.

In a machining apparatus, complete control of the movement, stopping, speed and displacement of a tool mounted on a rotating face plate is achieved by using a first motor to cause rotation of the face plate, causing the first motor to rotate a ring gear along with the face plate, controlling the relative speeds of the face plate and the ring gear by means of a second motor and a differential mechanism, and moving the tool on the face plate in response to a difference in the rotational speeds of the face plate and the ring gear.

A vehicular power transmitting system including an oil pump constructed to sufficiently reduce a required drive torque. A high-pressure-port discharge amount of first and second high-pressure passages of the oil pump is determined such that an amount of consumption of working oil of relatively high pressure can be afforded only by the high-pressure-port discharge amount, during steady-state running of a vehicle in which engine speed is not lower than a predetermined threshold value corresponding to a predetermined lowest target input shaft speed of a continuously variable transmission for its shifting control. The pressure of the working oil discharged from first and second low-pressure discharge passages is kept at a predetermined low level, and the required drive torque of the oil pump is sufficiently reduced.

An LCD device includes a reflective area in each pixel. A reflection film having a convex-concave surface is provided in the reflective area, film in cross section configuration is formed. Each pixel includes a pixel electrode and a common electrode for applying a lateral electric field on a LC layer. The inclination angle of the reflection film has an inclination angle distribution, wherein the angle component in an area corresponding to the electrodes has a lower angle distribution than the angle components in an area corresponding to a gap between adjacent two of the electrodes.
