摘要： In a repeater control device (6) for controlling a communication repeater (2) that has a beamforming function and relays a wireless communication signal including communication data addressed from a transmission device (3) to a reception device (4), the repeater control device (6) includes: a parameter determination unit that determines a gain adjustment value for adjusting input power to an amplifier that amplifies the wireless communication signal relayed by the communication repeater (2), on the basis of an evaluation value indicating communication quality in the reception device (4) and calculated on the basis of: state information indicating a state of the communication repeater (2); a beam pattern requested when the communication repeater (2) transmits the wireless communication signal to the reception device (4); transmission path information indicating a state of a transmission path between the communication repeater (2) and the reception device (4); and reception device information indicating a state of the reception device (4).

摘要： A calculation circuit (10) includes: a conversion unit (100) that divides a quantized signal into a first bit string and a second bit string, and converts the first bit string into a sequence including two or more bits and representing a numerical value by a ratio of 1 present therein; a calculation unit (200) that calculates the sequence converted by the conversion unit (100) by stochastic signal processing using a combinational circuit; and a reconversion unit (300) that adds a ratio of 1 present in a sequence after calculation by the calculation unit (200) and a value obtained by multiplying the second bit string by a number represented by the first bit string, and performs reconversion into a quantized signal.

摘要： A filter device (100) includes: a plurality of delay units (1-1 to 1-N) connected in series to give a delay to an input signal and output a delayed signal; a plurality of multiplication units (2-0 to 2-N) that multiply the delayed signal by a filter coefficient generated based on a predetermined value and a multiplying factor adjustment value; a coefficient adjustment unit (3) that, when a multiplication result obtained by multiplying the predetermined value by the multiplying factor adjustment value exceeds a maximum value of a representation range of the filter coefficient, divides the multiplication result exceeding the maximum value by the maximum value, and outputs a quotient of the division as a coefficient adjustment value; a signal conversion unit (4) that outputs a signal obtained by adding after-filter-coefficient-multiplication signals outputted by the multiplication units and an adjusted signal obtained by adjusting a corresponding delayed signal using the coefficient adjustment value; and a division unit (5) that generates an output signal by dividing the signal outputted by the signal conversion unit by the multiplying factor adjustment value.

摘要： A network management device (100) according to the present invention includes a metric calculation unit (101) that calculates, using location information of multiple nodes constituting a network, metrics for respective combinations of the nodes, a false detection determination unit (103) that determines, using the metrics and using link estimation information, which is information indicating a combination of nodes presumed that has a link therebetween, a falsely detected link corresponding to a combination of nodes indicated as having a link therebetween in the link estimation information, but presumed that has no link therebetween in reality, and a non-detection determination unit (105) that determines, using the metrics and the link estimation information, an undetected link corresponding to a combination of nodes indicated as having no link therebetween in the link estimation information, but presumed that has a link therebetween in reality.
