A charge calculation method executed by a processor included in a computer to execute a process, the process includes determining a degree of possibility that a virtual machine having redundant configuration exists in a plurality of virtual machines that provide a service, calculating a difference of charges for using the service before and after a first virtual machine among the plurality of virtual machines is migrated to an another location different from a location where the first virtual machine is located, and displaying the degree of possibility and the difference with respect to the service.

Non-transitory computer-readable recording medium and charge calculation method

A base station includes a determining unit, and a change unit. The determining unit determines, for each terminal, whether reception quality of an uplink signal from the terminal is equal to or smaller than a certain threshold. The change unit performs first processing or second processing when the reception quality is equal to or smaller than the certain threshold. The first processing is the processing of instructing a first terminal, a terminal of a transmission source of an uplink signal, to change the frequency of the uplink signal of the first terminal to the frequency of either an uplink or a downlink signal assigned to each terminal. The second processing is the processing of changing the frequency of a downlink signal identical to that of the uplink signal from the first terminal to the frequency of either an uplink or a downlink signal assigned to each terminal.

Base station, radio communications system, and processing method in base station

A receiver including: a memory, and a processor configured to calculate a plurality of soft decision values based on a received symbol to which a plurality of bits are mapped, to select at least one first soft decision value of the plurality of soft decision values, to calculate at least one relative value of at least one second soft decision value of the plurality of soft decision values other than the at least one first soft decision value, based on the at least one first soft decision value, to store the at least one first soft decision value and the at least one relative value, in the memory, and to estimate the plurality of bits based on the at least one first soft decision value and the at least one relative value which are stored in the memory.

Receiver and receiving method

An error correcting code decoding device includes a first decoding circuit, a word-length reduction circuit configured to reduce bit lengths of a first external values corresponding to a plurality of bits obtained after decoding process performed by the first decoding circuit a first predetermined number of times and to reduce bit lengths of words included in word string, and a second decoding circuit configured to decode the bit string by executing a decoding process a second predetermined number of times for calculating second external values and posterior values of the bits included in the bit string in accordance with the word string including the words having the reduced bit lengths using the first external values having the reduced bit lengths as second prior probabilities that corresponding bits among the plurality of bits are the predetermined value.
