    Abstract: Transmission power relative to a propagation path having a variation in gain is controlled to increase communication channel capacity, and a data rate is controlled in accordance with the variation of the increased communication channel capacity. In order to increase the communication channel capacity, the transmission power is determined so that the sum of noise power (=received noise power/propagation path gain) converted into one at a transmitter and the transmission power becomes constant. As a result, contrary to the background art, the transmission power is controlled to be reduced when the propagation path gain decreases and to be increased when the propagation path gain increases.

    Abstract: In a radio communication apparatus, a MIMO system deciding section of a transmitter unit decides an object MIMO communication system with reference to a CQI value and a measured rate table while an AMC table controlling section selects an object MCS value according to the decided MIMO communication system and CQI value. The AMC table controlling section changes the MCS value step by step according to a transmission count and a result (success/failure) of the communication. If the communication (receiving) is successful or if the transmission count reaches the maximum value, the controlling section updates the mean value of the measured rate table. At this time, based on a value estimated from the combination of the MIMO communication system, the encoding system, and the modulating system that are used currently, the controlling section changes the reference for selecting another combination that are not used currently.

    Abstract: A radio communication system includes a first radio station for dividing codewords into communication units and transmitting the divided codewords by modulating them in every communication unit, and a second radio station for coupling and decoding signals obtained by demodulating the communication units. The radio stations have common information of first bits, equal to maximum bits per symbol of the communication units, and an encoding type list. The first station modulates and transmits the communication units with a modulation type with second bits. The second radio station receives the communication units modulated by the first radio station, demodulates the communication units with a modulation type with third bits, combines and decodes the demodulated signals with encoding types in the encoding type list, and obtains a result of the decoding, as reception information, by an encoding type in which no error is detected in the result of decoding.

    Abstract: A method for suppressing the peak-to-average power ratio (PAPR) while limiting deterioration in signal characteristics in wireless communication devices utilizing wireless communication methods (OFDM method, MIMO method) for multiplexing and sending multiple signals. A weight calculator unit sets a large weight for transmit signals whose channel quality is poor, relative to the weight of each base component based on the acquired channel quality. A peak detector unit detects the peak from the signal string after unitary conversion, and extracts a distortion component to apply for suppressing the peak. A peak suppression signal generation unit calculates the peak signal from the distortion component and weight of each base component, to add to each base component, and adds the peak suppression signal to each base component prior to unitary transformation.
