A method is provided for applying a visual classification scheme to a map. A target region comprising a plurality of display units is identified within the map. It is then determined whether all of the display units within the target region can be assigned to the same class based on interpolated data values obtained for only a subset of the display units within the target region. If the determination is positive, then all of the display units within the target region are assigned to the same class and a visual indicator is assigned to each display unit in the target region based on the class to which the display unit was assigned. If the determination is negative, then the target region is divided into a plurality of subdivided target regions and the foregoing method is applied to each of the subdivided target regions.

Data interpolation and classification method for map data visualization

A base station device, method, and communication system are disclosed. The base station includes a covariance matrix obtaining unit forming a covariance matrix of an interference vector and a noise vector from received signals from multiple user equipment; a ratio calculation and comparison unit that calculates a relative ratio between the interference and the noise in the received signals based on the covariance matrix and compares the ratio with a predetermined threshold; an adjusting unit that reduces values of non-diagonal elements in the covariance matrix when the ratio is less than the predetermined threshold; an equalizer unit that performs equalization based on the covariance matrix using an Interference Rejection Combining algorithm when the ratio is greater than or equal to the predetermined threshold, and equalizes the received signals based on the adjusted covariance matrix using a Minimum Mean Square Error algorithm when the ratio is less than the predetermined threshold.

Base station device, method thereof, and communication system thereof

A method for wireless communication between a base station and a plurality of subscriber stations is described wherein a communication capacity is partitioned in resource units at least by code multiplexing, which resource units are distributed by the base station over said devices, wherein data from each subscriber station is spread by means of a signature sequence, characterized in that multiple resource units assigned to a common subscriber station have the same signature sequence.
