    摘要: To provide an adaptive array antenna capable of increasing resolution of a variable beam direction of the antenna without increasing a calculation amount in arithmetic processing unit for optimally controlling a variable phase shifter. A parasitic element-equipped adaptive array antenna (100) includes n (n is an integer equal to or greater than 2) parasitic antenna elements (1011 to 101n), (n−1) fed antenna elements (1021 to 102n−1) which are coupled to the parasitic antenna elements (1011 to 101n) by electromagnetic fields, and (n−1) variable phase shifters (1041 to 104n−1) which change the phases of radio frequency signals to be supplied to the respective fed antenna elements (1021 to 102n−1). Each of the fed antenna elements (1021 to 102n−1) is arranged astride at least two of the parasitic antenna elements (1011 to 101n).

    摘要: At least one recognized keyword is presented to a user, and the keyword is corrected appropriately upon receipt of a correction for the presented result. A standby-word dictionary used for recognition of uttered speech is generated according to a result of the correction to recognize the uttered speech. Therefore, even if recognized keywords contain an error, the error can be corrected and uttered speech can be accurately recognized.

    摘要: A wavelength division multiplexing device comprises a detection unit to detect the low-frequency signal in the optical signal; and a control unit to control to make the dispersion compensator perform a compensation operation by determining that the optical signal is being input when a low-frequency signal is detected in the optical signal in the detection unit, and to control to stop a compensation operation of the dispersion compensator by determining that there is an input break of the optical signal when a low-frequency signal is not detected in the optical signal in the detection unit.
