摘要： A frequency multiplier is constructed to input an input signal to a transistor through an input matching circuit and to output a multiplied output signal from the transistor through a reflecting type fundamental wave signal band suppressing circuit and an output matching circuit. A transmission line produces a standing wave and is disposed between the output terminal of the transistor and the input terminal of the reflecting type fundamental wave signal band suppressing circuit. Because the voltage acting on the output terminal of the transistor consequently increases, the transistor operates at a point at which the nonlinearity of its input-output characteristic is greater and the output power of the multiplied output signal increases.

摘要： A reception apparatus, method and a program using the reception method are provided to prevent degradation of reception quality due to interference. In a reception apparatus, an ADC samples data rIq[k] and rQq[k]. Based on the sampled data, a level detector finds an interference evaluation value Cc[l] for each OFDM symbol by counting the number of times one of the data rIq[k]q and rQq[kq] is clipped to the maximum output range of the ADC. When the interference evaluation value Cc[l] is greater than or equal to an interference decision value thc, a weighting control section corrects a soft-decision value wl,m,n by multiplying it by a weighting factor γc so as to decrease contribution of an error correction code to decoding.

摘要： When a terminal station receives a beacon in a channel f(i), it registers a MAC address included in the beacon in a registration table with an association with the channel f(i), then registers channels in which the same MAC address is registered, and the number of the channels in the registration table. By this processing, channels usable in a base station and the number of the channels usable are designated without need of adding, to a packet, information indicating the channels usable and the number of the channels usable.

摘要： A diversity OFDM communication is performed between a base terminal and a mobile terminal, both having a horizontal polarization antenna and a vertical polarization antenna forming two transmission channels. In the base terminal, data signals to be transmitted are divided into two channels to transmit the data signals through either one of the channels having a higher transmission performance for each sub-carrier. Common pilot signals are transmitted through both channels. The data signals received by the mobile terminal are phase-adjusted using the common pilot signals. The phase-adjusted data signals in both channels are synthesized and then demodulated.

摘要： After the OFDM signal for MMAC is received by a receiving unit , an FFT processing unit converts such OFDM signal into the signal Y(l, k) in the frequency axis direction. A data extracting unit extracts a data signal Y(l, kd) and a pilot extracting unit extracts a pilot signal Y(l, kp). A complex dividing unit divides the extracted pilot signal with a pilot signal X(l, kp) having the identical amplitude and phase as that in the transmitting side. An interpolating unit performs a linear interpolation by using a transmission path response H(l, kp) of the pilot signal in order to calculate the transmission path estimation value H′(l, k) of the data signal. A complex dividing unit divides the extracted data signal with the transmission path estimation value of the data signal in order to calculate the data signal Y′(l, kd) that is compensated in the amplitude and phase.

摘要： A soft decision value correction method can detect interference occurring in a desired wave and correct a soft decision value where a received power difference between the desired wave and an interference wave is small. A receiver and a program capable of performing the soft decision value correction method are provided. In the receiver an EVM calculator sets a detection distance for a primary modulation symbol of the first subcarrier in the first OFDM symbol as a reference, and calculates an evaluation value ΔEl,m that is an index of a distance between the primary modulation symbol of the reception signal and the reference. When the evaluation value ΔEl,m is greater than or equal to a normal threshold, a weighting controller infers that interference occurred, and multiplies a soft decision value Wl,m,n by a weighting factor to calculate a corrected soft decision value Vl,m,n.
