摘要： A receiver receives a signal from a transmitter via communication channels, informs the transmitter of channel state information, and includes a channel correlation value computation unit that computes a correlation value assigned to each channel state information combination; a conversion input data generation unit that determines a channel state information combination having a relatively large correlation based on the correlation value, to be conversion input data; a time-to-frequency region conversion unit that converts the region of the conversion input data from a time region to a frequency region; an information compressing unit that compresses information of a frequency component included in the conversion input data obtained by the time-to-frequency region conversion unit; and a transmitting unit that sends the transmitter, information-compressed data obtained by the information compressing unit and information used for isolating the channel state information items included in the conversion input data.

摘要： A channel state information compressing apparatus includes a time-to-frequency region converter that converts a region for channel state information which indicates a state of each communication channel from a time region to a frequency region; and an adaptive selector that selects each frequency component to be included in compressed data based on electric power of the frequency component from among frequency region data obtained by the time-to-frequency region converter. The channel state information compressing apparatus outputs the compressed data consisting of each selected frequency component, and information for identifying each frequency component which forms the compressed data.
