Abstract:
1. A wireless communication device, comprising: a measurement device configured to successively measure, at variable time intervals Δt, signal quality values C[t] of a wireless signal received by the wireless communication device, wherein C[t] denotes a signal quality value of the received wireless signal measured at time t; a mean-value calculator configured to calculate mean value μ of the successively-measured signal quality values C[t]; a standard-deviation calculator configured to calculate standard deviation σ of the successively-measured signal quality values C[t]; a determination section configured to make a determination as to whether the signal quality value C[t] at present time satisfies a predetermined inequality which represents that a signal quality value C[t] at arbitrary time lies within k times the standard deviations σ away from the mean value μ, wherein k denotes a region coefficient; and an adaptive controller configured to control lengths of the time intervals Δt for the measurement device, based on the determination made by the determination section, wherein the adaptive controller relatively shortens the time intervals Δt if the predetermined inequality is not satisfied.
