Title: Spectral shaping to reduce peak-to-average ratio in wireless communication
Inventor: KIM BYOUNG-HOON
IPC: H04L27/26
Filed: 2007-02-08
Abstract: Techniques for performing spectral shaping to achieve a desired peak-to-average ratio (PAR) are described. Spectral shaping may be selectively performed for a single-carrier frequency division multiplexing (SC-FDM) signal based on one or more criteria, e.g., in transmit power limited conditions and/or if a modulation scheme with lower PAR is unavailable. At least one parameter of a window function or spectral shaping filter may also be adjusted based on at least one characteristic of the SC-FDM signal. For example, the roll-off of the spectral shaping filter may be adjusted based on the modulation scheme and/or the number of subcarriers used for the SC-FDM signal.  A transmitter may perform spectral shaping on modulation symbols, if enabled, to obtain spectrally shaped symbols. Spectral shaping may be performed in the frequency domain either within an allocated bandwidth or with bandwidth expansion. The SC- FDM signal may be generated based on the spectrally shaped symbols.

Title: Pressure vessel fabricating method
Inventor: KAWAHARAZAKI YOSHINORI
IPC: B23K26/21
Filed: 2008-02-19
Abstract: Rib plates (2) are disposed in a cylindrical pressure vessel (vessel body (1)), and are joined to the inner wall surface of the pressure vessel while kept erected by welding from the outside of the wall of the pressure vessel. A resistance welding or a laser welding with less thermal effect is desirably used for the welding. Even small-sized, thin-walled pressure vessels can have an increased compressive strength by disposing and fixing the rib plates therein. Even the pressure vessels used as hydrogen storage alloy vessels can have an excellent strength against the expansion of alloy. Since the vessel can be easily manufactured, it can be mass-produced. Since the internal volume of the pressure vessel can be increased by reducing the plate thickness of the vessel and optimizing the shape of the ribs, volumetric efficiency as a hydrogen storage vessel can be increased.
