RECEPTION DEVICE, TRANSMISSION DEVICE, AND ADAPTIVE TRANSMISSION RATE CONTROL METHOD

摘要

In a receiver 20, a channel estimation unit 203 estimates channel characteristics of each channel, and a weight generation unit 204 generates a weight matrix used in equalization processing by an equalizer 206 in accordance with the estimated values of channel characteristics for each channel as estimated by the channel estimation unit 203. Furthermore, a likelihood calculation unit 205 calculates a likelihood indicating a degree of certainty for each transmission stream using the weight matrix generated by the weight generation unit 204, and an adaptive control unit 211 determines a transmission rate appropriate for transmission of a signal from a transmitter to the receiver 20 in accordance with the likelihood of each transmission stream calculated by the likelihood calculation unit 205, notifying the transmitter of the determined transmission rate.
