    摘要: The automatic gain control method with little being influenced of the unnecessary electric wave, even if strong unnecessary electric wave is near the frequency of input signal, is offered by carrying out change of the delay point level. The automatic gain control system with a scale of few circuit, having low noise property and high adjacent disturbance oppression property, is offered. When the IF AGC signal 112 is smaller than delay point level, the output agcerr of the signal level detector 614 is provided to the 1st loop filter 105. Since the IF AGC signal 112 provided to the IF AGC amplifier 608 is value responding to signal level of IF signal, output is fed back to this amplifier, and control of IF gain is performed automatically. On the other hand, when output of the 2nd loop filter 106 is “0”, output rfzero of the 2nd comparator 108 is set to 1, and “0” is provided to the 2nd loop filter 106. When the output of the 2nd loop filter 106 is not “0”, it is set to “0”, fixed value-rfdump is provided to the 2nd loop filter 106, and the output of the 2nd comparator 108 is converged when output of this loop filter became “0.” For this reason, the RFAGC signal 113 provided to the RF AGC amplifier 602 is set to “0”, and gain of the RF AGC amplifier 602 is fixed to maximum value.

    摘要: A demodulation circuit receives an OFDM transmit signal containing an information carrier, an additive-information transmission carrier, and a reception-synchronization pilot signal to convert these carriers and signal into frequency-axial data. The information carrier transmits information data. The additive-information transmission carrier and the reception-synchronization pilot signal have a lower multi-valued modulation degree than the information carrier. A differential detection circuit conducts detection processing by using a detection-subject symbol of a plurality of symbols indicated at a predetermined interval in the same frequency range and a symbol ahead that detection-subject symbol by a predetermined time in either one output of the additive-information transmission carrier and the reception-synchronization pilot signal output from the demodulation circuit. A first S/N ratio generating circuit generates an S/N ratio based on a detection output provided from the differential detection circuit. The S/N ratio indicates the reception quality of the OFDM transmit signal.

    摘要: An information processing terminal includes: circuitry to receive from a management system via a network, a candidate identifier of each one of one or more candidate counterpart information processing terminals that are previously registered for the information processing terminal; and to determine, in response to acceptance of an identifier that has been input, whether the accepted identifier matches any one of the candidate identifiers being received. Based on a determination indicating that the accepted identifier matches any one of the candidate identifiers, the circuitry transmits to the management system first request information requesting to start communication with the candidate counterpart information processing terminal identified with the accepted identifier. Based on a determination indicating that the accepted identifier does not match any one of the candidate identifiers, transmit to the management system second request information requesting to start communication with a counterpart information processing terminal identified with the accepted identifier, the circuitry transmits the second request information including destination information that differs from destination information included in the first request information.
