摘要： The present invention includes steps of, determining a search starting position; setting a center position, and a first position and a second position with a distance provided therebetween; obtaining a measurement point group including measurement points of the center position, the first position, and the second position; and determining a measurement point closest to the tip portion in the measurement point group based on positions of the measurement points in a second direction and selecting a position of the measurement point in a first direction as a selected position. When the measurement point group is obtained initially after the determination of the search starting position, the search starting position is set as the center position; and when the measurement point group is obtained after the selection of the selected position, the selected position is set as the center position. The distance is narrowed for every selection of the selected position.

摘要： In a time-interleaved AD converter which combines together low-speed high-resolution AD converters for effective high speed operation, various deterioration factors possessed by each of the converters, including DC offset, conversion gain error, sampling timing error, and a frequency characteristic, need to be compensated. The compensation is performed through nonlinear filter operation in which a constant term is added to linear filter operation. A high-speed low-resolution AD converter is separately used, and through adaptive signal processing in which an output signal thereof is defined as an instruction signal, a compensation coefficient is calculated. In this condition, the compensation can be performed without the influence of quantization noise attributable to the high-speed low-resolution AD converter.

A communication system includes a plurality of base stations in order to provide communication among a mobile station, another mobile station and a communication link. The communication links for use in the communication are selected base on the channel quality of the communications links.

摘要： Even if traffic concentrates on a specific place in a cellular radio communication in which a base station communicates with its corresponding wireless terminal, power to be used up or consumed by the base station can be restricted. Further, the equality of communication is satisfactory and the need for a change in the conventional wireless terminal is eliminated. Therefore, two types of sectors corresponding to a wide range sector and narrow range sectors each overlapping with the wide range sector are defined in a multi-sector model. Further, a wide range antenna for the wide range sector and narrow range antennas for the narrow range sectors are separately prepared for the base station. Afterwards, signals are transmitted to wireless terminals located within the narrow range sectors by using both the wide range antenna and the narrow range antennas. In the case of CDMA in particular, the same signal is transmitted with respect to a traffic channel alone.
