摘要： According to one embodiment, a wireless communication apparatus includes a calculator and a controller. The calculator multiplies a first weighting factor by a first data signal to be transmitted on a first channel, the first weighting factor is based on a second weighting factor multiplied by a second data signal received on the first channel. The controller controls a transmission to transmit to a destination device a control signal if the first data signal transmitted to the partner device exists, and no second data signal to be transmitted on the first channel exists in the device.

摘要： In one embodiment, a wireless relay apparatus for replaying a signal processed by first encoding from a transmitting apparatus to a receiving apparatus is disclosed. The apparatus includes a demodulation unit, a decoding unit, a detection unit, an extraction unit, and an encoding unit. The demodulation unit demodulates a received signal. The decoding unit performs error correction decoding corresponding to the first encoding on the demodulated signal. The detection unit detects an error in a decoded signal. The extraction unit extracts a portion pertaining to information data from the demodulated signal by hard decision, if the detection unit detects an error. The encoding unit performs error correcting coding on the extracted portion pertaining to the information data with an error. The information data encoded by the encoding unit is transmitted.

摘要： There is provided with a radio communication apparatus for communicating with a receiver. A transmission rate control unit in the radio communication apparatus specifies a signal having small variation of a metric, which is an index for evaluating a channel of the signal, out of first to nth signals to be transmitted to the receiver. The transmission rate control unit controls a transmission rate of a specified signal based on a channel responses and a transmission weight of the specified signal and controls a transmission rate of each of other signals different from the specified signal out of the first to nth signals based on a relationship between a variation characteristic of a metric of the specified signal and a variation characteristic of a metric of each of the other signals.
