摘要： A radio unit and a baseband processing unit perform wireless communications with a plurality of base station apparatuses compatible with a plurality of wireless communication schemes, respectively. A battery remaining amount management unit inspects a remaining amount of battery to be supplied to the radio unit and the like. A control unit controls standby operations that the radio unit and the baseband processing unit are to perform on the plurality of wireless communication schemes, based on the remaining amount of battery inspected by the battery remaining amount management unit. The control unit defines degrees of priority for the plurality of wireless communication schemes, respectively. As the remaining amount of battery becomes low, the control unit sets long a time interval of the standby operation for a base station compatible with a wireless communication scheme having a low degree of priority.

摘要： A correction unit corrects the phases of received multicarrier signals, respectively, carrier by carrier. A combining unit and a computing unit performs adaptive array processing on the corrected multicarrier signals on a carrier-by-carrier basis. A derivation unit derives, carrier by carrier, a phase for correction to be used by the correction unit, based on error in the multicarrier signals which have undergone the adaptive array processing. The derivation unit updates a frequency for correction about a carrier to which a known signal is assigned, based on error in the carrier, so as to derive a phase for correction and the derivation unit also derives a phase for correction, based on the error in the carrier and the phase for correction in a carrier to which the known signal is assigned.

摘要： A data rate is to be determined depending on circumstances. A control unit (30) transmits, at a predetermined frequency, a request signal by which to supply information on a data rate to a targeted radio apparatus compatible with a variable data rate. The control unit (30) receives rate information from the targeted radio apparatus. The control unit (30) sets a data rate used in the case of transmitting data, based on the information on a data rate contained in the rate information. The control unit (30) identifies the reliability level of the data rate contained in the rate information. And when the reliability level is low, the control unit (30) lowers the frequency at which the rate request signal is transmitted.

摘要： An adaptive controller for an ESPAR antenna randomly perturbs a bias voltage vector V(n) composed of elements of bias voltage values Vm by a random vector R(n) generated by a random number generator, compares an objective function value J(n) of a cross correlation coefficient for a bias voltage vector V(n) before the perturbation with an objective function value J(n+1) of a cross correlation coefficient for a bias voltage vector V(n+1) after the perturbation, and selects and sets the bias voltage Vm corresponding to that when the cross correlation coefficient increases before and after the perturbation. Then the adaptive controller repeats the random perturbation and setting from the bias voltage of respective varactor diodes. This leads to that it is not necessary to provide a long training sequence signal, and the control process can be executed with learning so that a performance can be improved every iteration for search.
